Abstract:
1. A process for making 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) from 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) comprising: (a) isomerization of HCFO-1233xf to yield HCFO-1233zd; wherein the isomerization reaction of HCFO-1233xf is conducted in a vapor phase reactor charged with an isomerization catalyst comprising fluorinated chromia catalyst pellets; and wherein the isomerization reaction is carried out at 0.0 psig and at 350° C. to attain a HCFO-1233xf conversion of about 50%.
