Abstract
Disclosed is a process for producing 1,2-dichloro-3,3,3-trifluoropropene, which is characterized by that 1-halogeno-3,3,3-trifluoropropene represented by the general formula [1]:(In the formula, X represents a fluorine atom, chlorine atom or bromine atom.) is reacted with chlorine in a gas phase in the presence of a catalyst. It is possible by this process to produce 1,2-dichloro-3,3,3-trifluoropropene in an industrial scale with good yield by using 1-halogeno-3,3,3-trifluoropropene, which is available with a low price, as the raw material.
