        Anhydrous hydrogen fluoride

        CAS No.: 7664-39-3

        Molecular formula: HF

        Molecular weight: 20.01

        Nature: colorless fuming liquid. The relative density is 0.987. Melting point - 83.1°C. The boiling point is 19.54°C. It is easy to gasify under reduced pressure or high temperature. It is highly corrosive and can corrode glass and damage other silicon-containing substances, causing severe skin burns. When dissolved in water, it is intensely exothermic to form hydrofluoric acid. It has high chemical activity and strong water absorption, can be combined with various metals and their oxides, and can be fluorinated with organic substances.

        Uses: It is the raw material for the production of refrigerant "Freon", fluorine resin, organic fluoride and fluorine. It can be used as a catalyst for organic synthesis such as alkylation, polymerization, cyclization and isomerization in chemical production. It is also used for the extraction of corrosive formations and rare earth elements and radioactive elements when mining certain deposits. It is a raw material for the manufacture of uranium hexafluoride in the atomic energy industry and nuclear weapons production. It is also a raw material for the production of rocket fuels and additives. It can also be used for corroding glass and impregnating wood.

        Standard: National Standard GB 7746-2011
