Production

It was first prepared in 1901 by Frédéric Swarts, the Belgian chemist who was the first to prepare chlorofluorocarbons in 1892. Swarts used the reaction of zinc with 1,1-difluoro-2-bromoethane. It is produced industrially by two routes, one being the mercury-catalyzed reaction of acetylene and hydrogen fluoride:[2]

HC≡CH + HF → CH2=CHF

It is also prepared from 1,1-chlorofluoroethane:

CH3CHClF → CH2=CHF + HCl
