Process for producing 1,1,2,3-tetrachloropropene

A process is disclosed for preparing 1,1,2,3-tetrachloropropene comprising allylic rearrangement of 2,3,3,3-tetrachloropropene using a substantially anhydrous ferric chloride catalyst. Alternatively, 1,1,2,3- tetrachloropropene is prepared by dehydrochlorination of 1,1,1,2,3- pentachloropropane usin...

Zusammenfassung:A process is disclosed for preparing 1,1,2,3-tetrachloropropene comprising allylic rearrangement of 2,3,3,3-tetrachloropropene using a substantially anhydrous ferric chloride catalyst. Alternatively, 1,1,2,3- tetrachloropropene is prepared by dehydrochlorination of 1,1,1,2,3- pentachloropropane using a ferric chloride catalyst. Process schemes commencing with the preparation of the precursor 1,1,1,3- terachloropropane by reaction of ethylene with carbon tetrachloride are also disclosed.
