Vinylidene Chloride


(1,1-dichloroethylene, CH2= CC12), a colorless liquid that has an odor resembling that of chloroform; Tb = 31.7° C. Density at 20° C, 1.212 g/cm3. The explosive limit of mixtures with air is 7-16 percent by volume. Vinylidene chloride polymerizes spontaneously in air; therefore it is stored in the presence of inhibitors such as hydroquinone.

Vinylidene chloride is made by dehydrochlorination of 1,1,2-trichloroethane (-100° C):


Vinylidene chloride is used to make polyvinylidene chloride and copolymers with vinyl chloride, acrylonitrile, and other technologically important copolymers.
