Character CAS No:7664-39-3 HS code: 28111100
Anhydrous hydrogen fluoride is colorless, transparent
liquid in the low-temperature. Boiling point is 19.4℃, melting point is -83.37℃. Critical temperature is 230.2℃; Critical pressure is 64 atm. Relative molecular weight is 20.01.The liquid density is 0.987 g/cm3 (20℃); Gas density is 0.991g/L (0℃). It can easily volatilize to smog under room and common temperature. Owing to its active chemical feature, it can react with alkaline, metal, oxide and silicate etc.

Storage and Transportation
Anhydrous hydrogen fluoride should be stored in draughty storeroom. Donít shine for
a long time and mix with inflammable and explosives. It should be treated as Grade A inorganic acid corrosive goods in transportation.
It is a strong oxidant and sole raw material for making the element of fluorine
It is important main raw material for inorganic Fluoride and all kinds of organic fluoride.
The use of fluorosilicates: metal surface treatment agent, the oil recovery additive.
As etchant for glass and metal cleaner.
It is used to produce fluorine plastic and fluorine rubber
