Vinyl fluoride is anorganic halide with the chemical formula C2H3F. It is a colorless gas with a faintether-like odor. It is used as themonomeric precursor to thefluoropolymerpolyvinylfluoride.
It was first prepared in 1901 by Frédéric Swarts, the Belgian chemist who was the first to preparechlorofluorocarbons in 1892. Swarts used the reaction ofzinc with 1,1-difluoro-2-bromoethane. It is produced industrially by two routes, one being the mercury-catalyzed reaction ofacetylene andhydrogen fluoride:[2]
It is also prepared from 1,1-chlorofluoroethane:
Vinyl fluoride is classified as anIARC Group 2A carcinogen (likely to causecancer in humans).
Its critical point is at 54.8 °C (328 K) and 5.24 MPa. Itsmolecular dipole moment is 1.4 Debye andheat of vaporization is 361 kJ/kg.
