Potassium hydroxide 90%

Potassium hydroxide 90% SGS accept bag or drum packaging

Potassium Hydroxide, commonly called caustic potash with formula KOH, is a caustic compound of strong alkaline chemical dissolving readily in water, giving off much heat and forming a caustic solution. It is a white deliquescent solid in the form of pellets obtained by concentration of purified electrolytic potassium hydroxide solution with very low chloride content. It reacts violently with acid and is corrosive in moist air toward metals such as zinc, aluminium, tin and lead forming a combustible, explosive gas. It absorbs rapidly carbon dioxide and water from air. Contact with moisture or water will generate heat. Sodium hydroxide (Caustic soda) and potassium hydroxide (Caustic potash) are the two most important caustics. They are closely resembles in chemical properties and applications, e.g., in manufacturing liquid soap, in bleaching, and in manufacturing chemicals. Potassium hydroxide is the largest-volume potassium chemical for non-fertilizer use. Potassium Hydroxide is used in chemical manufacturing including potassium carbonate and other potassium chemicals, fertilizers, phosphates, agrochemicals, alkaline batteries and dyes

Applications: It is widely used in the production of potassium carbonate including KHCO3, potassium soaps,detergents, fine cosmetic, potassium hydrogen phosphate, potassium permanganate, medical intermediate, liquid fertilizers, synthetic rubber, ABS resin, natural rubber emulsion, paper agent, fermentation,  cresol, de-sulfuration in petroleum refining, bio-fuel and alkaline battery.
