Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite, and soda pulping which is the least ecologically hazardous utilizing sodium hydroxide or anthraquinone. Caustic soda is added to increase the pH in the pulping process of fibers. The higher pH of the paper-fiber solution causes the fibers to smoothen and swell, which is important for the grinding process of the fibers.

In 2014, Pittsburgh water crisis was caused by unauthorized switching of anti-corrosion agent from soda ash to caustic soda. The city had been using soda ash for decades as a corrosion control chemical. Soda ash's alkalinity helps the metals to be less corrosive. It also has another property that leaves a solid residue which encourages mineral buildup as a protective layer within the interior surface of the pipes.

A points failure was later found to be responsible. Preliminary investigation indicated that there was probably no sabotage. In January 2008 two men, Wayne Cook and Steven Robinson were convicted in Manchester of sending miniature bottles of vodka contaminated with caustic soda and threatening to kill English people 'with no hesitation or compunction' by poisoning the country's water supply, echoing a previous threat in 2006. The accompanying letters were signed 'SNLA'.

Sodium tallowate, for example, is obtained by reacting tallow with sodium hydroxide (lye, caustic soda) or sodium carbonate (washing soda). It consists chiefly of a variable mixture of sodium salts of fatty acids, such as oleic and palmitic.Ruth Winter (2007): A Consumerýs Dictionary of Household, Yard and Office Chemicals: Complete Information About Harmful and Desirable Chemicals Found in Everyday Home Products, Yard Poisons, and Office Polluters. 364 pages.

The production of the paper has caused environmental problems such as the overstripping of trees for bark and the use of chemicals which wind up in the Cazones River. The problematic chemicals are caustic soda, used to soften the bark and industrial dyes. The Fiesta del Pueblo or Town Festival occurs annually in San Pablito. It begins the week after Holy Week ends and lasts for fifteen days.

Later, Hamilton Castner improved the process aluminium manufacturing and devised the electrolysis of brine in large mercury cells for the production of chlorine and caustic soda, effectively founding the chlor-alkali industry with Karl Kellner in 1892. The next year, Paul L. Hulin patented filter-press type electrochemical cells in France. Charles Frederick Burgess developed the electrolytic refining of iron ca. 1904 and later ran a successful battery company.

Martynellis was found to have purchased 60 lbs of caustic soda in the fortnight preceding Borynski's disappearance. A month after Borynski's disappearance Martynellis was found collapsed at his home. Martynellis claimed that he had been visited by two men who ordered him to 'keep quiet priest'. Martynellis had no external injuries, and police declined to confirm that he had been attacked, but confirmed that they were not searching for an assailant.

Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations and hydroxide anions . Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air.

There has recently been a considerable increase in the use of chemical paint removers in paste or liquid form; as a rule these contain some alkali, such as lime or caustic soda. The preparation is brushed on to the paint required to be removed, and in the course of from ten minutes to half an hour the paint becomes so soft that it can readily be scraped off.

Bund wall failures have occurred in the UK, such as at Warrington, Cheshire in 1994. A polypropylene tank holding about 30 tonnes of 40% aqueous caustic soda sprang a leak about halfway down the main wall. The corrosive fluid jetted out over the bund wall, causing great damage to the surrounding factory and adjacent premises. The bunding at Buncefield also failed to contain petrol and fire fighting water after the initial explosion and subsequent fire.

Shaking the flask causes oxygen present in the head space air to dissolve in the solution and oxidize the leuco-methylene blue back to its colored form again. Another variation uses methylene blue in water, glucose, and caustic soda (NaOH). In the past, it was thought that the reaction occurred by the oxidation of an aldehyde group to a carboxylic acid under alkaline conditions. For instance, glucose would be oxidized to gluconate by oxygen.

Solutions less than 40% are classified as a moderate oxidizing hazard (NFPA 430, 2000). Household bleach and pool chlorinator solutions are typically stabilized by a significant concentration of lye (caustic soda, NaOH) as part of the manufacturing reaction. This additive will by itself cause caustic irritation or burns due to defatting and saponification of skin oils and destruction of tissue. The slippery feel of bleach on skin is due to this process.

Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area, that fifteen grams of it has the equivalent surface area of the Melbourne Cricket Ground (). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution.

Therefore, this accumulating carbon dioxide must be removed from the breathing cycle. For the general function of this sort of breathing set, see rebreather. The absorbent used is almost always sodalime, or a material based on sodalime, but in former times slaked lime or quicklime or caustic soda was sometimes used. Submarine escape sets had a mouthpiece, so the user had to also wear a noseclip to avoid breathing water through his nose.

Tuck was granted for a "submarine vessel" in 1884. His submarine prototype, the Peacemaker, was tested with mixed success in 1884, 1885 and 1886 in New York's harbor. In its final form, it was powered by a chemical reaction based on caustic soda and it was armed with electrically fused buoyant "torpedoes" (), explosive charges that were intended to be planted under enemy ships. In 1888, the US government announced a competition for submarine designs.

After World War II Ray Evans, TR's son, led the company to decentralize its operations. In Deer Park, Houston, Texas, in 1946 a new plant was built to produce Chlorine and Caustic soda. In 1948 the company moved its headquarters from Pittsburgh to Cleveland, Ohio. During the 1950s a third plant was constructed in Muscle Shoals, Alabama, helping the company continue to enlarge its range of products, expanding to produce plastics and chemicals for agriculture.

When he discovered that the audiences in Halychyna had expected blind bandurists, he tried to blind himself by spraying caustic soda in his eyes. He returned to central Ukraine settling in Kiev where he made a living teaching bandura and re-selling banduras. Many of his students joined the Kiev Bandurist Capella in its second incarnation from 1924. He was a participant at the Xth historic-ethnographic concert held in Kiev in 1928.

The elute solution, normally consisting of caustic soda (the electrolyte), cyanide and water circulates through the loaded carbon, extracting gold and other metals. The loaded solution passes through an electro winning cell where the gold and other metals are attached to cathodes, made up of wire wool, by electrolysis. The solution then passes back through the loaded carbon, extracting more gold and other metals. This process continues until the carbon has been stripped.

Bulgaria is among Europe's largest producers of lead, zinc and copper, and produces around ten percent of the world's hydraulic machinery. Other products include machine tools, caustic soda, nuclear energy, military hardware/munitions and many other finished and semi- finished products. The country is the largest electricity exporter in south- eastern Europe. About 14% of the total industrial production relates to machine building, and 20% of the workforce is employed in this field.

Solid anhydrous sodium hypochlorite is unstable and decomposes explosively. A non-explosive hydrated solid is available for laboratory use, but must be kept refrigerated to avoid decomposition.) Liquid bleach usually contains also some sodium hydroxide (caustic soda or soda lye, ), intended to keep the solution alkaline. Sodium chloride (table salt, ) is often present too, and plays no role in the product's action. Sodium chloride and hydroxide are normal residues from the main production processes.

Chemical works at Weston Point, Runcorn The town's chemical industry was dominated for many years by ICI's Chlor Chemical division. But since 2001, Inovyn (a wholly owned subsidiary of Ineos) has operated the extensive chemical works in the west of the town, employing 750 people in 2020. In Runcorn, Invoyn manufactures chlorine, caustic soda and chlorinated derivatives. It also produces salt, made from brine transported by pipeline from the saltfields of central Cheshire, and sulphuric acid.

Nikolos Landia's main works are devoted to chemical thermodynamics. In 1945, he developed a new method for obtaining calcined and caustic soda from sodium sulfate, coal and water vapour. In 1946-1962, he defined the thermodynamic characteristics of a number of inorganic compounds and chemical processes. He created a method for accurate calculation of the high-temperature heat capacity of solid inorganic compounds, widely used in thermodynamic studies of high-temperature metallurgical processes, silicate technology, and inorganic technology.

Large Rochelle salt crystal grown aboard Skylab The starting material is tartar with a minimum tartaric acid content 68 %. This is first dissolved in water or in the mother liquor of a previous batch. It is then saponified with hot caustic soda to pH 8, decolorized with activated charcoal, and chemically purified before being filtered. The filtrate is evaporated to 42 °Bé at 100 °C, and passed to granulators in which Seignette's salt crystallizes on slow cooling.

Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive. Chlorine can also be produced by the electrolysis of a solution of potassium chloride, in which case the co- products are hydrogen and caustic potash (potassium hydroxide).

The first practical electric razor, the Sunbeam "Shavemaster" and the Remington "Close Shaver" made available in the US in 1937 and in Canada shortly thereafter. With a base of caustic soda, the world's first oven cleaner, Easy-Off, was invented in Regina in 1932 by Herbert McCool and manufactured in his home in that city until 1946, when production shifted to Iberville, Quebec. The product has since become the most popular oven cleaner in the world.

Old drawing of a chloralkali process plant (Edgewood, Maryland) The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride solutions. It is the technology used to produce chlorine and sodium hydroxide (lye/caustic soda), which are commodity chemicals required by industry. 35 million tons of chlorine were prepared by this process in 1987. The chlorine and sodium hydroxide produced in this process are widely used in the chemical industry.

Three years later they designed and built their own home in Farnworth, where they lived until 1949. They had four children: a daughter, Valerie; an adopted son, Peter; and sons Dennis and Roderick. The Central Laboratory's focus at this time was on the chemistry of chlorine and fluorine. Electrolysis of salt water produced chlorine and sodium hydroxide (caustic soda), but there was not as much demand for the chlorine, so ICI was eager to create new products using chlorine that it could sell.

Fondo Nacional para el Fomento de las Artesanías (FONART), the Universidad Autónoma Metropolitana-Iztapalapa, the Universidad Veracruzana and the Instituto de Artesanías e Industrias Populares de Puebla have been working on ways to make amate paper making more sustainable. One aspect is to manage the collection of bark. Another is to find a substitute for caustic soda to soften and prepare the fibers without losing quality. Not only is the soda polluting, it has had negative effects on artisans' health.

This enormous time saving is achieved by heating to with the addition of caustic soda. The composition of the additional ingredients, however, still remains a well-guarded secret of the approximately twenty picklers. These taste-enhancing ingredients, such as basil, lemon balm, grape leaves, cherry leaves or walnut leaves, give Spreewald gherkins their special sour, spicy taste. After the reunification of Germany in 1990, Spreewald gherkins were one of the few products from East Germany which were still available without interruption.

The addition of "peptising" substances (i.e. substances that break up and separate the clay particles and prevent them from coagulating again) can further reduce particle size. Such substances include caustic soda (NaOH), ammonia (NH3), potash (K2CO3) and polyphosphates such as calgon (NaPO3)6: these attach themselves to the clay particles with strong hydrogen bonds and thus prevent them, in a similar way to tensides, from rejoining and coagulating again. In other words, the clay particles are now in a state of colloid suspension.

Vat dyes characteristically require a reducing agent to solubilize them. The most common reducing agent is sodium dithionite (Na2S2O4), which converts the dye to its "leuco" form that is soluble. Once attached to the fabric, the leuco dye is then oxidized to the insoluble state which is intensely colored. Chemical reactions such as oxidation, reduction, pH control are often necessary; even the dissolution process necessitates measuring out appropriate quantities of caustic soda and sodium hydrosulphite in order to achieve reduction.

Only about 6% of the salt manufactured in the world is used in food. Of the remainder, 12% is used in water conditioning processes, 8% goes for de-icing highways and 6% is used in agriculture. The rest (68%) is used for manufacturing and other industrial processes, and sodium chloride is one of the largest inorganic raw materials used by volume. Its major chemical products are caustic soda and chlorine, which are separated by the electrolysis of a pure brine solution.

Water and sodium hydroxide detergent-based parts washers are considered to be an environmental improvement over the solvent- based cleaning methods. Hardware stores grade sodium hydroxide to be used as a type of drain cleaner. Paint stripping with caustic soda Sodium hydroxide is used in the home as a type of drain opener to unblock clogged drains, usually in the form of a dry crystal or as a thick liquid gel. The alkali dissolves greases to produce water soluble products.

Caustic soda is limited to smaller combustion units because it is more expensive than lime, but it has the advantage that it forms a solution rather than a slurry. This makes it easier to operate. It produces a "spent caustic" solution of sodium sulfite/bisulfite (depending on the pH), or sodium sulfate that must be disposed of. This is not a problem in a kraft pulp mill for example, where this can be a source of makeup chemicals to the recovery cycle.

The best-known story tells of a tragic mistake made by his mother while preparing a meal on 22 October, two days before his death. Pépe’s mother, who could not read, mistakenly exchanged caustic soda for salt when she made chorizos. The next day, Pépe took a sandwich containing the chorizo to work with him and consumed the corrosive compound. Of note, other relatives who had eaten the meal had also been hospitalized, but survived, and a cat that had consumed the chorizo died.

In the days after the explosion, there were intimations in the media of sabotage linked to a labor dispute. The vessel had been picketed in a Bay Area port and some of its crew harassed by maritime union pickets. The FBI intervened, but it was quickly determined that no point source explosion had occurred. Later it was found that the explosion probably resulted from holes in tank compartment bulkheads that allowed caustic soda to mix with zinc, forming deadly hydrogen gas that then exploded.

The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance. Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products.

Two Israeli trauma centers were opened in southern Israel near Gaza. ; June 18, 2007 :A Qassam rocket fired from Gaza struck a factory, containing hazardous materials, in Sderot. The attack resulted in a leak of gaseous caustic soda and prompted the response of police, fire-fighting forces, and teams specialized in dealing with hazardous materials who sealed the leak and removed the poisonous materials. ; June 20, 2007 :Nine Qassam rockets struck the western Negev injuring three with shrapnel and causing shock in at least seven reported cases.

The desalinated water is stabilized to protect downstream pipelines and storage, usually by adding lime or caustic soda to prevent corrosion of concrete-lined surfaces. Liming material is used to adjust pH between 6.8 and 8.1 to meet the potable water specifications, primarily for effective disinfection and for corrosion control. Remineralisation may be needed to replace minerals removed from the water by desalination. Although this process has proved to be costly and not very convenient if it is intended to meet mineral demand by humans and plants.

An estimated two-thirds of human-generated mercury comes from stationary combustion, mostly of coal. Other important human-generated sources include gold production, nonferrous metal production, cement production, waste disposal, human crematoria, caustic soda production, pig iron and steel production, mercury production (mostly for batteries), and biomass burning. Small independent gold-mining operation workers are at higher risk of mercury poisoning because of crude processing methods. Such is the danger for the galamsey in Ghana and similar workers known as orpailleurs in neighboring francophone countries.

Thereafter, he founded Adejumo Fam Brothers, trading assorted items such as gramophone records and decorative wares out of his store along Breadfruit, Lagos. The firm later expanded into importation of caustic soda and other industrial and water treatment chemicals. Beginning in 1974, Adejumo was head of the Nigerian Lawn Tennis Association for fifteen years and became one of the leading promoters of tennis in the country. Adejumo as chairman of the Nigerian Lawn Tennis Association was involved in the promotion of the 1976 Lagos WCT.

A close-up of Pears soap Pears soap was made using a process entirely different from that for other soaps. A mixture of tallow and other fats was saponified by an alkali. Clearly, this is currently caustic soda (sodium hydroxide), since the ingredients list shows sodium salts of fatty acids, but a chemist reports that in the 1960s, caustic potash (potassium hydroxide) was used. It has not been possible to determine what was used in the early days of the product, as the writings of Francis Pears mention only alkali in industrial methylated spirits.

Seventy-two irreparable devices were neutralised on-site by being drained into individual pits filled with caustic soda crystals. Despite being given a preservative covering the bombs continued to suffer in the damp Welsh climate and in 1951 twenty-one Bellman hangars were erected on the site to store the bombs. Finally in June 1954 it was decided to dispose of the entire stock because by then it was recognised that not only did the weapons have no military value but they had actually become a liability, which could only become worse as time passed.

He later testified that he performed facial surgery on himself and obliterated the fingerprint impressions on the tips of his fingers by the application of a caustic soda preparation. Piquett said Dillinger would have to pay $5,000 for the plastic surgery: $4,400 split between Piquett, Loeser and O'Leary, and $600 to Dr. Harold Cassidy, who would administer the anaesthetic. The procedure would take place at the home of Piquett's longtime friend, 67-year-old James Probasco, at the end of May. On May 28, Loeser was picked up at his home at 7:30 p.m.

In the 1960s it was the site of a new chemical industry, with plants producing fertilizer and caustic soda. Shijiazhuang also became an engineering base, with a tractor-accessory plant. There are important coal deposits at Jingxing and Huailu, now named Luquan, a few miles to the west in the foothills of the Taihang Mountains, which provide fuel for a thermal- generating plant supplying power to local industries. In 1967, Tianjin was again carved out of Hebei, remaining a separate entity today, and thus the provincial capital was moved to Baoding.

The basis for this was the production of pure chemicals, agents for agricultural pest control, and car paints, finishes, and waxes. After that, the Association started developing a chemical complex including electrolysis for chlorine and caustic soda production, and a plant for the production of viscose staple fibres. As part of the expansion, a coal-burning plant for steam production, a water purification station and a hydroelectric power plant on the Elbe were built by the end of 1946. In 1945, the Association, including its plant in Neratovice, was nationalised.

The second step in the refining process is the separation of the free fatty acids (FFA) from the oil through alkaline neutralization. Depending on the type of oil being processed, there can be either two or three stages during neutralization, where three stages are done to produce a higher quality oil. Cottonseed oil goes through all three stages of neutralization. The first stage of neutralization occurs when caustic soda, or sodium hydroxide is added to the oil after being pumped through a strainer and heated to 133 °C.

Pittsburgh's water lines include a significant number of lead pipes which have inevitably eroded to a certain degree within the past few decades. In 2014, the Pittsburgh Water and Sewer Authority (PWSA) broke state law by switching from soda ash to caustic soda as an anti-corrosion treatment without first receiving the necessary approval and permits from the Pennsylvania Department of Environmental Protection (DEP) as required by Pennsylvania. This unauthorized switch sparked an increase in erosion levels that made the water's lead levels spike beyond the federal limit of 15 ppm.

A circulating water plant or circulating water system is an arrangement of flow of water in fossil-fuel power station, chemical plants and in oil refineries. The system is required because various industrial process plants uses heat exchanger, and also for active fire protection measures. In chemical plants, for example in caustic soda production, water is needed in bulk quantity for preparation of brine. The circulating water system in any plant consists of a circulator pump, which develops an appropriate hydraulic head, and pipelines to circulate the water in the entire plant.

During the 6AM to 2PM shift at the factory, workers were required to take a routine sample from each of the LPG storage tanks. A team composed of a plant operator, the shift fireman and a laboratory technician were taking a sample from sphere no.443. The operator, due to the fact that he had only a single valve spanner, opened the valves in the incorrect order. This caused the release of a small amount of caustic soda and a small amount of gas when he opened the lower valve.

Caustic paint removers, typically sodium hydroxide (also known as lye or caustic soda), work by breaking down the chemical bonds of the paint, usually by hydrolysis of the chain bonds of the polymers forming the paint. Caustic removers must be neutralized or the new finish will fail prematurely. In addition, several side effects and health risks must be taken into account in using caustic paint removers. Such caustic aqueous solutions are typically used by antique dealers who aim to restore old furniture by stripping off worn varnishes, for example.

Since regular atmosphere is about 21% oxygen and <1% carbon dioxide and the respiration of the fruit adds 1 mole of carbon dioxide for every mole of oxygen produced, the combined value of oxygen and carbon dioxide will equal 21% in a sealed storage room of fruit, if only respiration is allowed to alter the room atmosphere. Once carbon dioxide increased above 7%, the benefits began to disappear as carbon dioxide toxicity began to occur. However, controlling carbon dioxide levels meant flushing with outside air or using expensive caustic soda, a skin and eye irritant.

Palmitic acid is used to produce soaps, cosmetics, and industrial mold release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Because it is inexpensive and adds texture and "mouth feel" to processed foods (convenience food), palmitic acid and its sodium salt find wide use in foodstuffs.

In addition to Cunneen, former drummers include: Dave Triebwasser (Pond) and Rudy Apodaca. John Blender and Regina LaRocca (Oily Bloodmen, Caustic Soda, M99) also played bass for the band. The Obituaries toured throughout the Western U.S. and shared the bill with many notable bands during their career, including: Green River, Mother Love Bone, Sonic Youth, Nick Cave, Alex Chilton, The Gits, Babes In Toyland, The Descendents, Dead Moon, Soundgarden and Nirvana. The band reformed for several shows in 2007 in conjunction with the release of a retrospective CD with Nelson, Landoll, LaRocca, and Mahone.

Corrosive compounds, especially O2 and CO2 must be removed, usually by use of a deaerator. Residual amounts can be removed chemically, by use of oxygen scavengers. Additionally, feed water is typically alkalized to a pH of 9.0 or higher, to reduce oxidation and to support the formation of a stable layer of magnetite on the water-side surface of the boiler, protecting the material underneath from further corrosion. This is usually done by dosing alkaline agents into the feed water, such as sodium hydroxide (caustic soda) or ammonia.

The Dead Sea Works was founded in 1952 as a state-owned enterprise based on the remnants of the Palestine Potash Company. In 1995, the company was privatized and it is now owned by Israel Chemicals. From the Dead Sea brine, Israel produces (2001) 1.77 million tons potash, 206,000 tons elemental bromine, 44,900 tons caustic soda, 25,000 tons magnesium metal, and sodium chloride. Israeli companies generate around US$3 billion annually from the sale of Dead Sea minerals (primarily potash and bromine), and from other products that are derived from Dead Sea Minerals.

After the outbreak of the First World War, he became responsible for designing and constructing plants to manufacture caustic soda and chlorine via the electrolysis of brine. He visited USA with Dr. J. T. Conroy to investigate the electrolytic chlorine processes in use there. He was appointed an Officer of the Order of the British Empire in the 1918 Birthday Honours for his work during the war. With E. M. Hollingsworth he designed West Bank Power Station in the 1920s to supply power to the factories of the United Alkali Company.

Indupa (Indústrias Patagonicas) was established in Río Negro Province (Argentina) on September 16, 1948, and became a leading local producer of chlorine, Polyvinyl chloride resins (PVC), and caustic soda. It relocated operations to the petrochemical center in Bahía Blanca in 1986; but an economic crisis in subsequent years forced it into government receivership in 1993. Re-privatized in 1995 to a consortium led by Dow Chemical, Indupa was acquired in 1996 by Brussels-based Solvay, which owns a 51% stake. The company, in turn, acquired Solvay do Brasil and its Santo André facility (opened in 1941) in 1998.

Other trees such as mulberry do not have to mature as much. The pressure to provide large quantities of bark means that it is taken from younger trees as well. This is negatively affecting the ecosystem of northern Puebla and forcing harvesters to take bark from other species as well as from a wider range, moving into areas such as Tlaxco. Another problem is the introduction of caustic soda and other industrial chemicals into the process, which not only gets into the environment and water supply, can also directly poison artisans who do not handle it properly.

The factory was not well equipped to handle the gas created by the sudden addition of water to the MIC tank. The MIC tank alarms had not been working for four years and there was only one manual back-up system, compared to a four-stage system used in the United States. The flare tower and several vent gas scrubbers had been out of service for five months before the disaster. Only one gas scrubber was operating: it could not treat such a large amount of MIC with sodium hydroxide (caustic soda), which would have brought the concentration down to a safe level.

Following the Nazi invasion of Poland in 1939 and the establishment of the Reichsgau Wartheland, from 1940 onwards many prisoners of war were stationed in Mątwy. From December 1942 to August 1943 this included a Jewish forced labour camp working in the caustic soda factory. Prisoner of war camps located here included a Heilag (repatriation camp) (closed September 1943), Stalag 391 (I D) (1941-December 1942), Oflag 10 (from December 1942), Oflag XXI-B (June - September 1943) and Stalag XXI-D (September - December 1943). Oflag 64 and Construction and Labour Battalion 146 for Soviet prisoners were also stationed here.

These vehicles were virtually silent, because the steam was not released into the atmosphere. A soda locomotive could run for several hours, but eventually the soda would become diluted and wouldn't produce enough heat to continue generating steam. For reconcentrating, the caustic soda was either transferred out of the boiler of the locomotive and boiled in open vats, or, rather more conveniently, by injecting superheated steam at a high enough temperature to boil off the water in solution. A stationary boiler would be hooked up and feed superheated steam through the soda to boil off the water and effectively recharge the soda.

Preparing for her departure, Setti came to visit Cianciulli one last time. Cianciulli offered Setti a glass of drugged wine, then killed her with an axe and dragged the body into a closet. There she cut it into nine parts, gathering the blood into a basin. Cianciulli described what happened next in her official statement: > I threw the pieces into a pot, added seven kilos of caustic soda, which I > had bought to make soap, and stirred the mixture until the pieces dissolved > in a thick, dark mush that I poured into several buckets and emptied in a > nearby septic tank.

According to Tijuana's Chief of Police, García was principally responsible in the late 2000s for the increase in the number of homicides in the city. Teodoro García is best known for running an extortion and kidnapping network, and is also known for dissolving the bodies of those who are in business with rival drug gangs by drowning them in caustic soda. Upon being arrested, García's lieutenant, Santiago Meza López — known as the Stew Maker, claimed to have dissolved over three hundred bodies this way in 2008. The Mexican Army stated that it believed Meza's claims to be true.

Initially, that new process was designed to utilize spent etchant streams from the electronic printed circuit board manufacturing industry as starting materials. There are two types of spent etching solutions from printed circuit board manufacturing operations: an acidic cupric chloride solution (CuCl2/HCl), and an alkaline cuprammine chloride solution (Cu(NH3)4Cl2). Tribasic copper chloride is generated by neutralization of either one of these two solutions (acidic or alkaline pathway), or by combination of these two solutions, a self-neutralization reaction. In the acidic pathway, the cupric chloride solution can be neutralized with caustic soda, or ammonia, lime, or other base.

The company was founded in 1855 by Henri Merle as a producer of caustic soda at a manufacturing facility in Salindres. Founded as Compagnie des Produits Chimiques Henri Merle the company was renamed in 1897 the Société des Produits Chimiques d'Alais et de la Camargue. The company first began producing aluminium metal in 1860 using a chemically- based process developed by Henri Sainte-Claire Deville in 1854 and was granted a 30-year monopoly by the French government. During World War I (1914–18) Tréfileries et Laminoirs du Havre (TLH) acquired a large stake in the Société d'Alais et de la Camargue.

Chlorine is produced from sodium chloride (common salt, NaCl) using electrolysis to separate the metallic sodium from the chlorine gas. Usually the salt is dissolved in water to produce a brine. By-products of any such chloralkali process are hydrogen (H2) and sodium hydroxide (NaOH), which is commonly called caustic soda or lye. By far the largest use of mercury in the late 20th century was in the mercury cell process (also called the Castner- Kellner process) where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide.

Kankesanthurai Cement Factory, Paranthan Caustic Soda Chemical Factory and Valaichchenai Paper Mill were opened during Ponnambalam's ministerial tenure. Ponnambalam's decision to join the UNP led government in 1948 caused a split in the ACTC. Eventually, in December 1949, the ACTC dissidents, led by Chelvanayakam, C. Vanniasingam and E. M. V. Naganathan, formed the Illankai Tamil Arasu Kachchi (ITAK, Federal Party). As Ceylon's two main parties, the UNP and Sri Lanka Freedom Party (SLFP), introduced policies, such as the Sinhala Only Act, which further discriminated against the country's minorities, ITAK's Tamil nationalism became more popular than the ACTC's conservatism.

Beech wood is an excellent firewood, easily split and burning for many hours with bright but calm flames. Slats of beech wood are washed in caustic soda to leach out any flavor or aroma characteristics and are spread around the bottom of fermentation tanks for Budweiser beer. This provides a complex surface on which the yeast can settle, so that it does not pile up, preventing yeast autolysis which would contribute off-flavors to the beer. Beech logs are burned to dry the malt used in some German smoked beers, giving the beers their typical flavor.

In May 2007 a series of letters threatening to contaminate food in Tesco stores unless he was paid ₤100,000 were sent to the company's offices in Dundee. This did not succeed so the blackmailer demanded executives transfer ₤200,000 into his bank account or he would put caustic soda in yoghurt sold in the store. The letters were signed "Arbuthnot, the sign is the spider" and had dead spiders taped to them. Some of them had text composed of letters cut out of a magazine and demanded that Tesco respond via an advertisement in the personal column in The Times.

The company Indian Rare Earths Limited (IREL) has developed a process to extract uranium from the Western and Eastern coastal dune sands of India. After pre-processing with high-intensity magnetic separators and fine grinding, the mineral sands (known as monazite), are digested with caustic soda at about and water. The hydroxide concentrate is further digested with concentrated hydrochloric acid to solubilise all hydroxides to form a feed solution composed of chlorides of uranium and other rare earth elements including thorium. The solution is subjected to liquid–liquid extraction with dual solvent systems to produce uranyl chloride and thorium oxalate.

Accessed 28 Apr 2012. These early mines simply processed the cryolite for its direct aluminum content and for sale to the Pennsylvania Salt Manufacturing Company, which used it to create caustic soda. The 1884 establishment of the Hall-Heroult Process, which depends on the rare cryolite but dramatically improved the extraction of aluminum from bauxite ore, increased the deposit's importance. The Ivittuut mining operations were a major factor in the American occupation of Greenland during World War II. After World War II, the cryolite was mined by the Danish firm Kryolitselskabet Øresund, which helped fund the establishment of Grønlandsfly, today's Air Greenland.

The cardboard bun hoax was a falsified news report broadcast in July 2007 on Beijing Television's BTV-7 (the Lifestyle Channel). In the report, footage implied that local vendors were selling pork buns, a common breakfast food, filled with a composite of 60% caustic soda-soaked cardboard and 40% fatty pork. Coming after several highly publicized food safety incidents in China, the report was widely believed and sparked public outrage. On July 18, 2007 Chinese law enforcement officials reported that they had detained Zi Beijia (訾北佳), a local freelance reporter, for allegedly faking the news report.

The tradition of indigo dyeing goes back centuries in West Africa. The earliest known example is a cap from the Dogon kingdom in Mali dating to the 11th century, dyed in the oniko style. However, by the end of the 1930s the spread of synthetic indigo and caustic soda and an influx of new less skilled entrants caused quality problems and a still-present collapse in demand. Though the more complex and beautiful starch resist designs continued to be produced until the early 1970s, and despite a revival prompted largely by the interest of US Peace Corps workers in the 1960s, never regained their earlier popularity.

As it was a new industry, no textbooks existed to guide them, but the situation was saved when someone found in a cupboard, all the exact and detailed records of Beer's experiments. Later, Edwin Beer became disgruntled by what he perceived as all the "incorrect histories" of the man-made fibre industries, and in 1962 he and his wife Phoebe published "The Beginning of Rayon". This book evokes a world where the practice of science was not yet a respectable profession. Beer had to work for long, irregular hours, at even more irregular pay, in a laboratory, formerly a stable, slimy with caustic soda, and reeking of carbon di-sulfide.

Sir Humphry Davy Pieces of potassium metal Potassium metal was first isolated in 1807 by Humphry Davy, who derived it by electrolysis of molten KOH with the newly discovered voltaic pile. Potassium was the first metal that was isolated by electrolysis. Later in the same year, Davy reported extraction of the metal sodium from a mineral derivative (caustic soda, NaOH, or lye) rather than a plant salt, by a similar technique, demonstrating that the elements, and thus the salts, are different. Although the production of potassium and sodium metal should have shown that both are elements, it took some time before this view was universally accepted.

As of 2009, there were at least 200 craftsmen in the trade in the town with a yearly production value of about 500,000 pesos. The production has caused environmental damage as trees are stripped for bark and chemicals from the process such as caustic soda make their way into the San Pedro River. There have been efforts to plant and grow new types of trees that provide back in 5 or 6 years as well as the introduction of nonpolluting chemicals.

A crystal of sodium acetate trihydrate (length 1.7 centimetres) For laboratory use, sodium acetate is inexpensive and usually purchased instead of being synthesized. It is sometimes produced in a laboratory experiment by the reaction of acetic acid, commonly in the 5–8% solution known as vinegar, with sodium carbonate ("washing soda"), sodium bicarbonate ("baking soda"), or sodium hydroxide ("lye", or "caustic soda"). Any of these reactions produce sodium acetate and water. When a sodium and carbonate ion-containing compound is used as the reactant, the carbonate anion from sodium bicarbonate or carbonate, reacts with hydrogen from the carboxyl group (-COOH) in acetic acid, forming carbonic acid.

The surrounding water undergoes a hydrolysis reaction that produces a sodium hydroxide (caustic soda) build-up near the battery's anode face. This results in the liquefactive necrosis of the tissue, a process whereby the tissue effectively is melted away by the alkaline solution. Severe complications can occur, such as erosion into nearby structures like the trachea or major blood vessels, the latter of which can cause fatal bleeds. While the only cure for an esophageal impaction is endoscopic removal, a 2018 study from Children's Hospital of Philadelphia by Rachel R. Anfang and colleagues found that early and frequent ingestion of honey or sucralfate suspension prior to removal can reduce the injury severity to a significant degree.

The company was founded in 1903 as "the Development and Funding Company" by Elon Huntington Hooker, of Rochester, NY. Hooker created the company to utilize the Townsend cell to electrolyse salt into chlorine and sodium hydroxide (NaOH), also known as "caustic soda" and "lye," in a chloralkali process. Elmer Sperry, founder of Sperry Electric, and Leo Baekeland, inventor of Bakelite and Velox photographic paper, consulted for Hooker to improve the design of the cell. The company was sited in Niagara Falls, NY because of the low-cost electricity from the Niagara Falls power project (completed in 1895), the abundance of salt from nearby mines, and availability of water from the Niagara River.

A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations, and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today than they once were, now that the toxic effects of mercury and its compounds are more widely understood. It is still used as an ingredient in dental amalgams. In the late 20th century the largest use of mercury was in the mercury cell process (also called the Castner-Kellner process) in the production of chlorine and caustic soda.

In 1944, the American poet Winfield Townley Scott was working as a reporter in Rhode Island when a sailor displayed his skull trophy in the newspaper office. This led to the poem The U.S. sailor with the Japanese skull, which described one method for preparation of skulls (the head is skinned, towed in a net behind a ship to clean and polish it, and in the end scrubbed with caustic soda). Charles Lindbergh refers in his diary entries to several instances of mutilations. For example, in the entry for August 14, 1944, he notes a conversation he had with a Marine officer, who claimed that he had seen many Japanese corpses with an ear or nose cut off.

A mixture of rubber and gasoline can be used in the field to produce a crude incendiary bomb. A mixture of white phosphorus and jelled gasoline also produces a flammable mixture. Other mixtures include: LA-60 in which crude latex is combined with caustic soda, coconut oil, and water, crepe rubber (CR) in which crude latex reduced to a solid by precipitation and kneading, LA-100 in which crude latex is dried until it is 100% solid, smoked rubber sheets (SR) in which crude latex that has been dried over a fire until it is 100% solid. When used with these fillers, the bomb uses a black powder charge to ignite and scatter the incendiary materials.

Conductive level sensors are ideal for the point level detection of a wide range of conductive liquids such as water, and is especially well suited for highly corrosive liquids such as caustic soda, hydrochloric acid, nitric acid, ferric chloride, and similar liquids. For those conductive liquids that are corrosive, the sensor’s electrodes need to be constructed from titanium, Hastelloy B or C, or 316 stainless steel and insulated with spacers, separators or holders of ceramic, polyethylene and Teflon-based materials. Depending on their design, multiple electrodes of differing lengths can be used with one holder. Since corrosive liquids become more aggressive as temperature and pressure increase, these extreme conditions need to be considered when specifying these sensors.

There are two operational thermal power plants as of December 2016: The Hrazdan Thermal Power Plant with an installed capacity of 1100 MW, and the Yerevan Thermal Power Plant with an installed capacity of 250 MW. The Hrazdan Thermal Power Plant, which is owned by the Russian Federation, produced 12.3% of the electricity produced in Armenia in 2014. Recent upgrades made to the Yerevan Thermal Power Plant have increased its efficiency to almost 70% by reducing the consumption of fuel, sulfuric acid, and caustic soda, and by reducing emission levels. For its power production, it uses natural gas supplied from Iran and exchanges it with the electricity produced by the plant, while using the surplus energy for domestic consumption.

The Mississauga train derailment of 1979, also known as the Mississauga Miracle occurred on Saturday, November 10, 1979, in Mississauga, Ontario, Canada, when a 106-car CP Rail freight train carrying chemicals and explosives including styrene, toluene, propane, caustic soda, and chlorine from Windsor, Ontario derailed near the intersection of Mavis Road and Dundas Street in Mississauga, Ontario. As a result of the derailment, more than 200,000 people were evacuated in what was the largest peacetime evacuation in North America until the New Orleans evacuations during Hurricane Katrina. There were no deaths resulting from the incident. This was the last major explosion in the Greater Toronto Area until the Sunrise Propane blast in 2008.

In recent years, companies such as Syncrude and Suncor have switched to much cheaper shovel-and-truck operations using the biggest power shovels (at least ) and dump trucks () in the world. This has held production costs to around US$27 per barrel of synthetic crude oil despite rising energy and labour costs. After excavation, hot water and caustic soda (sodium hydroxide) is added to the sand, and the resulting slurry is piped to the extraction plant where it is agitated and the oil skimmed from the top. Provided that the water chemistry is appropriate to allow bitumen to separate from sand and clay, the combination of hot water and agitation releases bitumen from the oil sand, and allows small air bubbles to attach to the bitumen droplets.

From there he moved, probably in 861, to the same post in Egypt. To boost the province's revenue, he took a series of measures, including doubling the kharāj and the jizya and raising new taxes (mukūs)—a move widely denounced as un-Quranic, demanding the payment of taxes each lunar year (instead of the longer solar year), imposing a state monopoly on caustic soda, and depriving the Christian clergy of their traditional tax privileges and exemptions. As a result, he became both the most powerful, as well as the most hated man in Egypt, and was constantly escorted by a hundred young bodyguards. His fall began in September 868, with the arrival of a new governor of Egypt, Ahmad ibn Tulun.

Kiranjit was convicted of murder in December 1989. At the trial, the prosecution argued that although on the night of the event she had been threatened with a hot poker, the fact that she waited until her husband had gone to sleep was evidence that she had time to "cool off" and weigh to a nicety her actions. In addition, the prosecution claimed that her prior knowledge to mix caustic soda with petrol to create napalm was not common knowledge and so was proof that she had planned her husband's murder. Her counsel did not make any claims about the violence she later claimed she had endured, and the prosecution suggested that Kiranjit was motivated by jealousy because of her husband's repeated affairs.

He returned to Stoke Prior in 1848 and in 1850 he moved to Widnes. Here he established an alkali works on the opposite side of the Sankey Canal from Hutchinson's No 1 factory near to Widnes Dock. Gossage's alkali production was on a small scale and he spent time in various experiments, including extracting sulphur from copper ores, extracting copper from iron pyrites, concentrating sulphuric acid and manufacturing caustic soda from the black ash liquor resulting from the Leblanc process. Following another experiment, consisting of adding sodium silicate to soda ash, he discovered he could produce soap at a much lower cost than by the methods existing at the time and in 1855 he gave up making alkali to set up his soap works.

Philip Drackett, born to a Cleveland shipbuilding family in 1856, decided to cut his own swath, apprenticing to a pharmacist while in school, and opening his own Cleveland drugstore upon his marriage. He was fascinated by chemicals, though and eventually sold the drugstore, becoming a sales representative for drug supply houses, first in Chattanooga, Tennessee, then in Cincinnati. At the age of 54, his sons grown, he and his wife Sallie opened their own brokerage, providing chemicals with such items as soda ash, caustic soda, chlorinated lime, and denatured alcohol to janitor-supply companies, laundries, and other industrial users throughout the midwest, south and west. He did well; five years later, his sons Harry and Philip Jr. were working for the firm, and instead of selling bulk chemicals, they were packaging them.

Another time he used a whole-body plastic bag to keep the rain off (and nearly suffocated a few minutes later). He has ridden round a race-track in the wrong direction, and collided with Ogri (Malcolm's boundless incompetence versus Ogri's massive adequacy is a classic encounter between the irresistible force and the immovable object); he has borrowed Ogri's bike to ride around a race-track and fallen off through following the map of another course. Ogri once gave Malcolm a handful of engine parts to de- grease; he dropped them into a bath of caustic soda, unaware that the chemical dissolved aluminium. He gave him most of an engine to de-coke; Malcolm put it in the washing machine, destroying both the engine and the washing machine.

In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process. After separation of the residue by filtering, gibbsite is precipitated when the liquid is cooled and then seeded with fine-grained aluminum hydroxide crystals from previous extractions. The precipitation may take several days without addition of seed crystals. The extraction process converts the aluminium oxide in the ore to soluble sodium aluminate, 2NaAlO2, according to the chemical equation: :Al2O3 \+ 2 NaOH → 2 NaAlO2 \+ H2O This treatment also dissolves silica, forming sodium silicate : :2 NaOH + SiO2 → Na2SiO3 \+ H2O The other components of Bauxite, however, do not dissolve.

Anodic protection (AP) is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell and controlling the electrode potential in an zone where the metal is passive. Anodic protection is used to protect metals that exhibit passivation in environments whereby the current density in the freely corroding state is significantly higher than the current density in the passive state over a wide range of potentials.Néstor Pérez " Electrochemistry and corrosion science", Kluwer Academic Publishers, 2004 (google books).Anodic protection : theory and practice in the prevention of corrosion, by Olen L. Riggs, Jr. and Carl E. Locke, Plenum Press, New York, 1981 Anodic protection is used for carbon steel storage tanks containing extreme pH environments including concentrated sulfuric acid and 50 percent caustic soda where cathodic protection is not suitable due to very high current requirements.

Although The Soap Myth is a work of fiction, it is, in the words of the program, "inspired by real people and real events as well as an article written by Josh Rolnick in Moment magazine profiling Holocaust survivor Morris Spitzer."Program, Dog Run Rep, South Street Seaport Foremost among the play's historical inspirations is the evidence that the Nazi regime had a program at the Danzig Anatomic Institute in 1944 to develop a process for the mass-production of soap from the fat of Jews being slaughtered in Nazi extermination camps, and produced soap in small quantities at a nearby concentration camp. In a dramatic moment, the players re-enact testimony from the Nuremberg Trials, including this recipe: > 5 kilos of human fat are mixed with 10 liters of water and 500 or 1,000 > grams of caustic soda. All this is boiled 2 or 3 hours and then cooled.

Hydrochloric acid is sometimes used, but is much less damaging. Aqueous solutions of strongly alkaline materials, such as caustic soda (sodium hydroxide), are used as well, particularly in areas where strong acids are controlled substances. The long term consequences of these attacks may include blindness, as well as eye burns, with severe permanent scarring of the face and body, along with far- reaching social, psychological, and economic difficulties. Today, acid attacks are reported in many parts of the world, though more commonly in developing countries. Between 1999 and 2013, a total of 3,512 Bangladeshi people were attacked with acid with the rate of cases declining by 15%-20% every year since 2002 based on strict legislation against perpetrators and regulation of acid sales. In India acid attacks are at an all-time high and increasing every year with 250-300 reported incidents every year while the "actual number could exceed 1,000, according to Acid Survivors' Trust International".

The ion-selective membrane (B) allows the counterion Na+ to freely flow across, but prevents anions such as hydroxide (OH−) and chloride from diffusing across. At the cathode (C), water is reduced to hydroxide and hydrogen gas. The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas. Saturated brine is passed into the first chamber of the cell where the chloride ions are oxidised at the anode, losing electrons to become chlorine gas (A in figure): :2Cl− → + 2e− At the cathode, positive hydrogen ions pulled from water molecules are reduced by the electrons provided by the electrolytic current, to hydrogen gas, releasing hydroxide ions into the solution (C in figure): :2 + 2e− → H2 \+ 2OH− The ion- permeable ion exchange membrane at the center of the cell allows the sodium ions (Na+) to pass to the second chamber where they react with the hydroxide ions to produce caustic soda (NaOH) (B in figure).
