Description :
Anhydrous potassium fluoride is a white powder with high activity and deliquescence. The relative density is 2.48. The melting point is 858 ℃, and the boiling point is 1505 ℃. The refractive index is 1.363. Soluble in water, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone. The aqueous solution is alkaline and can corrode glass and porcelain. This product is used for glass carving, food corrosion prevention and electroplating. It can be used as welding flux, pesticide, fluorinating agent of organic compounds, catalyst, absorbent, etc. It is also the raw material for preparing potassium hydrogen fluoride. At present, as an intermediate, it is widely used in pharmaceutical, pesticide and other industries. Its performance is manifested in high activity, high yield, low dosage and low by-product in fluorination reaction. Secondly, it is unnecessary to use expensive phase transfer catalyst in fluorination reaction.
