Document Type and Number:
WIPO Patent Application WO/2020/149365
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for easily and inexpensively producing (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223xd(Z)) from a composition which contains 1223xd(Z) and 1,1-dichloro-3,3,3-trifluoropropene (1223za). One embodiment of the present invention is a method for producing (Z)-1,2-dichloro-3,3,3-trifluoropropene (HCFO-1223xd(Z)). The method involves reducing the ratio of 1223za to 1223xd(Z) in the composition by contacting the composition, which contains 1223xd(Z) and 1,1-dichloro-3,3,3-trifluoropropene (HCFO-1223za), and a base with one another.
