Potassium Hydroxide (chemical formula: KOH, formula weight 56.1), white powder or flakes. Melting point is 380℃, boiling point is 1324℃, relative density is 2.04g/cm3, refractive index is n20/D1.421, vapour pressure is 1mmHg(719℃). Potassium hydroxide is strong alkali and it has corrosivity.  It can easily collect the moisture in the air then deliquescence, and absorb carbon dioxide then becomes potassium carbonate. It will cause a lot of heat when dissolving in the water, alcohol or dealing with acid.


1. Potassium Hydroxide can be used as desiccant, absorbent, making oxalic acid, sylvite, electronic plating, sculpture, lithography etc.
2. It can also be mainly used as the raw materials of potash production, such as potassium permanganate, potassium carbonate etc. In medical industry, it can be used in making potassium borohydride, spironolactone, ShaGan alcohol etc. In light industry, it can be used in making potash soap, alkaline storage battery, and cosmetics. In dyeing industry, it can be used in vat dyes. In textile industry, it can be used in printing and dyeing, whiten and mercerization. Potassium hydroxide can also be mainly used in manufacturing artificial fiber and polyester fiber.
