Molecular formula: KOH
Molecular weight: 56.11
Specifications:
Industrial grade potassium hydroxide content 90%; 95%
Physical and chemical properties:
· White powder or flake solid.
· Melting point 360 ~ 406 ℃, boiling point 1320 ~ 1324 ℃, relative density 2.044g/cm, flash point 52 ° F, refractive index N20 / D1 421, steam pressure 1mmhg (719 ℃).
· Highly alkaline and corrosive. It is very easy to absorb moisture in the air and deliquesce, and absorb carbon dioxide to form potassium carbonate.
