METHODS FOR PRODUCING 1-CHLORO-3,3,3-TRIFLUOROPROPENE FROM 2-CHLORO-3,3,3-TRIFLUOROPROPENE

摘要

The present invention provides processes for the production of HCFO-1233zd, 1- chloro-3,3,3-trifluoropropene, from the starting material, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf). In a first process, HCFO-1233zd is produced by the isomerization of HCFO-1233xf. In a second process, HCFO-1233zd is produced in a two-step procedure which includes (i) dehydrochlorination of HCFO-1233xf into trifluoropropyne; and (ii) hydrochlorination of the trifluoropropyne into HCFO-1233zd.
