1,1-Difluoroethylene, also known as vinylidene fluoride, is a hydrofluoroolefin. This a flammable gas is a polyfluorinated version of ethene. Global production in 1999 was approximately 33,000 metric tons.[1] It is primarily used in the production of fluoropolymers such as polyvinylidene fluoride.

Preparation

1,1-Difluoroethylene can be prepared by elimination reaction from a 1,1,1-trihaloethane compound, for example, loss of hydrogen chloride from 1-chloro-1,1-difluoroethane:.[2]
