Abstract

PURPOSE: To obtain the titled compound useful as a monomer simply in high yield at atmospheric pressure and a low temperature without requiring a surfactant, by dechlorinating and debrominating 1,1,2-trifluoro-2-chloro-1-bromoethane in the presence of a metallic dehalogenating agent and water.
CONSTITUTION: 1,1,2-Trifluoro-2-chloro-1-bromoethane expressed by the formula is dechlorinated and debrominated in the presence of a metallic dehalogenating agent, e.g. Zn, and water at 15W60°C, preferably 40W50°C, at atmospheric pressure to about 5atm to give trifluoroethylene. The amount of the metallic dehalogenating agent to be used is 1.1W1.5mol based on the compound expressed by the formula. The water used is capable of adjusting the temperature and acts as a solvent for a metallic halide formed in the reaction. The amount of the water is 2W10 times that of the compound expressed by the formula.
USE: A monomer for a functional material having improved piezoelectricity, pyroelectricity, etc. of a copolymer thereof with vinylidene fluoride and a monomer for a copolymer with an olefin containing fluorine.
