Industrial grade potassium hydroxide

2019-09-23 501

1、 Overview


Molecular formula Koh, molecular weight 56.11.

Properties: pure products are white orthorhombic crystals, and industrial products are white flakes or rods. Specific gravity 2.044, melting point 306.4 ℃, boiling point 1320-1324 ℃. It is easily soluble in water and releases a lot of heat when dissolved. It has strong hygroscopicity. It will absorb water and carbon dioxide in the air and turn into potassium carbonate. It has strong alkalinity and corrosivity, and its property is similar to caustic soda. It is necessary to avoid contact with human body to prevent burns!


2、 Purpose:

Potassium hydroxide is mainly used as raw material for other potassium salts, such as potassium permanganate, potassium carbonate, etc. Circuit board industry is used for stripping circuit ink.
