Description

A dichlorodifluoroethylene (systematically named dichlorodifluoroethene) is one of three compounds with the chemical formula C 2Cl 2F 2. Dichlorodifluoroethylenes are colourless gases, and are some of the simplest chlorodifluoroalkenes.
The structural isomers are used as intermediates or precursors in the production of other industrial chemicals.
