Vinyl fluoride(75-02-5) is an organic halide with the chemical formula CH2＝CHF. It is a colorless gas with a faint etherlike odor.
The Structure of Vinyl fluoride(75-02-5):
History
Vinyl fluoride(75-02-5) was first prepared in 1901 by Frédéric Swarts (the Belgian chemist who was the first to prepare CFCs in 1892) using the reaction of zinc with 1,1-difluoro-2-bromoethane. Now it is synthesized by the reaction of acetylene and hydrogen fluoride.
Uses
The principal use of Vinyl fluoride(75-02-5) is as the primary component in making polyvinyl fluoride, a polymer of the basic vinyl fluoride monomer.
Production
Vinyl fluoride (75-02-5), the monomer for poly(vinyl fluoride), is manufactured by addition of hydrogen fluoride to acetylene:
HC≡CH + HF →CH2＝CHF
