PRODUCTION METHOD OF 1,2-DIFLUOROETHYLENE

Provided is a production method of 1,2-difluoroethylene which can produce 1,2-difluoroethylene with high selectivity. This production method of 1,2-difluoroethylene comprises a step for performing a dehydrochlorination reaction of 1-chloro-1,2-difluoroethane in the presence or absence of a catalyst. The dehydrochlorination reaction is a gas-phase reaction or a liquid-phase reaction. According to the production method of the present disclosure, 1,2-difluoroethylene can be produced with high selectivity. 本发明提供一种1,2-二氟乙烯的制造方法，其能够以高的选择率制造1,2-二氟乙烯。本发明的1,2-二氟乙烯的制造方法包括在催化剂的存在下或不存在下进行1-氯-1,2-二氟乙烷的脱氯化氢反应的工序。上述脱氯化氢反应为气相反应或液相反应。根据本发明的制造方法，能够以高的选择率制造1,2-二氟乙烯。
