Vinylidene fluoride Use and Manufacturing

Methods of Manufacturing

1. The vinylidene fluoride ethane chlorination method uses dry acetylene to react with hydrofluoric acid in the presence of fluorosulfonic acid to produce 1, 1-difluoroethane, which is compressed, fractionated and purified to obtain refined 1, 1-di Ethylene fluoride is fully mixed with chlorine in a quantitative ratio and pyrolyzed at 650-680°C to generate crude vinylidene fluoride, and then compressed, fractionated and purified to obtain refined monomers. 2. Other methods Due to the development of the chlorofluoroalkane substitute industry in recent years, 1, 1, 1-trichloroethane can be used to produce 1, 1-difluoro-1-chloroethane by one-step reaction, and then thermally cracked to remove Hydrogen chloride.

Uses

Mainly used as monomer raw material for fluororesin and fluororubber
