Document Type and Number:
WIPO Patent Application WO/2020/246611
Kind Code:
A1
Abstract:
The present disclosure provides a method for producing a reaction gas containing R-1132(E) with higher selectivity than in conventional methods. More specifically, the present disclosure provides a method for producing a reaction gas containing (E)-1,2-difluoroethylene (R-1132(E)), wherein: (1) the method includes a step for subjecting a raw material gas containing at least one fluoromethane compound selected from the group consisting of chlorodifluoromethane (R-22), difluoromethane (R-32) and fluoromethane (R-41) to a reaction that includes thermal decomposition so as to obtain the reaction gas; and (2) the raw material gas has a water vapor content of 1 vol% or less.
