Lye Sodium hydroxide

Alkali Treatment. Caustic washing is the treatment of materials, usually products from petroleum refining, with solutions of caustic soda. The process consists of mixing a water solution of lye (sodium hydroxide or caustic soda) with a petroleum fraction. The treatment is carried out as soon as possible after the petroleum fraction is distilled, since contact with air forms free sulfur, which is corrosive and difficult to remove. The lye reacts either with any hydrogen sulfide present to form sodium sulfide, which is soluble in water, or with mercaptans, foUowed by oxidation, to form the less nocuous disulfides. 

When you boil glyceryl tristearate in lye (sodium hydroxide), you get sodium stearate and glycerin. When you remove the glycerin, you get soap. 

Today, soaps are made from fats and oils that react with lye (sodium hydroxide). Solid fats like coconut oil, palm oil, tallow (rendered beef fat), or lard (rendered pork fat), are used to form bars of soap that stay hard and resist dissolving in the water left in the soap dish. 

A solution of vinegar (acetic acid) is titrated with lye (sodium hydroxide) HC2H3O2 + OH - H20 + C2 H302 ... 

Sodium hydroxide is the most widely used strong base in the chemical industry. It exists as a white, odorless, crystalline solid at room temperature. Sodium hydroxide is a highly corrosive and toxic substance and is called caustic soda or lye. Sodium hydroxide is used as an alkali in the production of numerous products including detergents, paper, synthetic fabrics, cosmetics, and pharmaceuticals. It is the ingredient in many common cleaners, degreasers, drain cleaners, and personal care products. 

Today we no longer tinker with alchemy, and mercury has long been abandoned by hat manufacturers. But this doesn t mean that we don t still have to contend with mercury exposure. The chemical industry employs the metal as a catalyst, and mercury is an integral part of the process used to produce chlorine and lye (sodium hydroxide) from salt. It is also found in electrical switches, dental amalgams, batteries, detonators, and, of course, thermometers. 

Sodium hydroxide forms fused solid pieces, granules, rods, or powder. It rapidly absorbs moisture and carbon dioxide from the air. Solutions of sodium hydroxide are very corrosive to animal tissue, and aluminum. It has a melting point of 318 Celsius. Sodium hydroxide is very soluble in water and alcohol. It generates large amounts of heat when dissolving in water, or when mixed with acid. Sodium hydroxide is toxic. Handle sodium hydroxide with care. Sodium hydroxide is a widely available commercial chemical, which is sold under a variety of names such as Lye . Sodium hydroxide is prepared on an industrial scale in a procedure called the chloro-alkali process. In the chloro-alkali process, a sodium chloride solution is electrolysized in a special cell composed of two compartments separated by a porous membrane. Chlorine gas is produced at the positive anode, and sodium hydroxide forms at cathode. 

Start by grinding the ore to a fine powder. Then set it aside until we need it. Now prepare a strong alkali solution by dissolving lye (sodium hydroxide) into rainwater. A 20 to... 

NOTE If a gel does not form, add additional wax (up to 40% by volume) and repeat the above steps. If no gel forms with 40% wax, make a Lye solution by dissolving a small amount of Lye (Sodium Hydroxide) in an equal amount of water. Add this solution (1/2% by volume) to the gasoline wax mix and shake bottle until a gel forms. 

Some experts believe that hydrogen forms more compounds than any other element. These compounds include water, sucrose (table sugar), alcohols, vinegar (acetic acid), household lye (sodium hydroxide), drugs, fibers, dyes, plastics, and fuels. 

To get the best powder you ll want to remove the hulls. Put two ounces of water in a glass and pour in a teaspoonful of lye (sodium hydroxide) from any grocery store. Wait until it cools and put in one or two ounces beans. They float so put a weight on them to hold them under. Soak one hour. 

Oven drain cleaners Lye (sodium hydroxide) Severe damage to stomach and esophagus if swallowed. Also found in bathroom and toilet cleaners. 

Grandma made her soap by taking animal fat, adding it to water and lye (sodium hydroxide, NaOH), and boiling it in a huge iron kettle. The lye came from wood ashes. After cooking for hours, the soap rose to the top. It was then skimmed off and pressed into bars. However, Grandma didn t know much about reaction stoichiometry. She usually had an excess of lye, so her soap was very alkaline. 

The triglycerides obtained from animal fats have been used for a very long time as a source of soap. When fats are boiled with lye (sodium hydroxide) the ester linkages are cleaved by a process known as saponification (the term originates from the Latin word for soap, sapon, as does the modem French word for soap, savon) to yield the sodium salt of the fatty acid and the esterifying alcohol (glycerol). 

Aluminum metal reacts rapidly with highly basic solutions to liberate hydrogen gas and a large amount of heat. This reaction is utilized in a popular solid drain cleaner that is composed primarily of lye (sodium hydroxide) and aluminum granules. When wet, the mixture reacts as follows ... 

Sodium hypochlorite, NaClO, the main ingredient in household bleach, is produced by bubbling chlorine gas through a strong lye (sodium hydroxide, NaOH) solution. The following equation shows the reaction that occurs ... 

CHEMICAL INDUSTRY. Much of the salt is utilized in the manufacture of other chemicals. By passing an electric current through salt—electrolysis—it can be broken up into sodium metal and chlorine gas. The sodium can be used as a catalyst, or it can combine with other elements to form new chemicals such as sodium carbonate, sodium bicarbonate, and lye (sodium hydroxide). The chlorine formed by electrolysis can also be used to make other chemicals, or it can be employed in bleaching paper and textiles, or in disinfecting...
