Preparation of Chlorotrifluoroethylene: It is derived from the dechlorination of trifluorotrichloroethane. Generally, using zinc powder as dechlorination agent and methanol as solvent. The reaction temperature is 50-150 °C, the reaction pressure is 2.08MPa, and the reaction time is 3-4s. Consumption of raw materials is fixed: trifluorotrichloroethane 1830 kg / t, methanol (> 95%) 1080kg / t, zinc (> 95%) 840kg / t.

Uses of Chlorotrifluoroethylene: It can be polymerised to produce the plastic ECTFE. And it is used as raw material of fluorine plastic, fluorine rubber, refrigerant, CFCs oil and halothane anesthetic. Additionally, it reacts methanol to get (2-chloro-1,1,2-trifluoro-ethyl)-methyl ether. This reaction needs reagent KOH-solution at temperature of -80 °C.
