anhydrous hydrogen fluoride

anhydrous hydrogen fluoride Molecular formula: HF

anhydrous hydrogen fluoride Molecular weight: 20.01

anhydrous hydrogen fluoride Physical and chemical feature: AHF is a achromatic and transparent liquid under low temperature. Its boiling point is 19.4, the melting point is -83.37 and the specific gravity is 1.008g/cm³(25/4). It easily volatilizes into smog under room and common temperature. Owing to its active chemical feature, it can react on alkali, metal, oxide and silicate, etc. Under certain condition, it can be freely mixed with water into hydrofluoric acid with strong irritant smell, which will strongly corrode the eyes, ears, nose and laryngitis mucons membrane, Moreover it seriously corrodes human tooth and skeleton and calcificates them.

Technical Standard of AHF (GB7746-87)

Usage: AHF is widely used in atomic energy, chemical industry, petroleum, etc. It is a strong oxidant and basic raw material for making the element of fluorine, fluoride cold-producing medium, inorganic fluoride and all kinds of organic fluoride. It can also be used in making hydrofluoric acid for all kinds of use, the processing of black lead and catalyzer for organic compound as well as the making of hyalographic agent.

Packing: Steel cylinder 400L/320KG each.
