Potassium hydroxide

Potassium hydroxide (lat. Kalii hydroxidum) — an inorganic compound with the formula KOH. Trivial names: caustic potash, caustic potash and potassium hydroxide, potassium hydroxide, potassium lye, potassium lye. Colorless, very hygroscopic crystals, but hygroscopicity smaller than sodium hydroxide. Aqueous solutions of KOH have a strongly alkaline reaction.

Produced by electrolysis of KCl used in the production of liquid Soaps, to obtain various compounds of potassium. Hydroxide potassium is produced by electrolysis of KCl, usually with the use of mercury cathodes, which gives a product of high purity containing no impurity chlorides.

Potassium hydroxide is almost versatile chemical compound. Examples of materials and processes in which it is used: neutralization of acids, alkaline elements, catalysis, detergents tools, drilling fluids, dyes, fertilizers, manufacture of food products, gas treatment, metal manufacturing, oil refining, various organic and inorganic substances, production of paper, pesticides, pharmaceuticals, regulation of pH, potassium carbonate and other potassium compound, soap, synthetic rubber.

In the food industry is referred to as food Supplement E525. Is used as regulator of acidity, as a desiccant, and means for removing the skin of vegetables, roots and fruits. He also used as catalyst in some reactions. Also used to obtain methane, the absorption of acid gases and discovery of some cations in solutions.

A popular tool in the production of cosmetic product reacts with fatty oils and with splits mylive this oil. In zirconium production is used to obtain obezhirennogo zirconium hydroxide.

In the field of industrial washing based products of potassium hydroxide, heated to 50-60 °C, are used to purify products stainless steel from fat and other oily substances and residues machining. Used as electrolyte in alkaline (alkaline) batteries. Also used in resolutie — alternative the method of "burial" of bodies.

5% solution of potassium hydroxide is used in medicine for the treatment of warts. In the pictures is used as a component developers, toners, indicators thiosulfate and removal of the emulsion with photographic materials.

Potassium hydroxide - a very strong alkali. Pure effect on the skin and mucous membranes cauterizing way. Especially dangerous getting even the smallest particles of potassium hydroxide in the eye, so all the work with this substance should be carried out in rubber gloves and glasses. Hydroxide potassium destroys paper, leather and other materials of organic origin.

The potassium hydroxide is non-flammable and non-explosive, the degree of impact on the body relates to the substances of the 2nd class. It is poured in clean steel containers or barrels with a capacity of 100, 200, and 275 h Hard the potassium hydroxide is Packed into clean dry steel drums, type I or III, with a capacity of 50-180 dm3 and stored in covered unheated warehouses or under a canopy. The potassium hydroxide in the form of flakes allowed to pack in steel drums with a capacity of 50-180 dm3 with polyethylene inserts or in plastic bags. A solution of potassium hydroxide, are stored in special steel sealed containers.
