high purity potassium hydroxide

1.Properties

 

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.

 

 

White translucent crystal. massive white characters or Corynebacterium. Trade 2.044g/cm3 degrees. 360.4 ° C melting point. Boiling Point 1320 ~ 1324 ° C Soluble in water, ethanol, is not soluble in ether and ammonia. A strong corrosive water and pieces of the air and water that can be dissolved, and gradual absorption of carbon dioxide into potash. When dissolved in water emit large amounts of hot, was strongly alkaline aqueous solution.

 

 

 

2.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.

3.Storage /transportion

 

It should be stored in a dry and ventilated warehouse and avoid sundry odors pollution. Sunlight and rain should be prevented during transportation.
