Abstract:
1. A process for isomerizing a (hydro)fluoropropene, the process comprising contacting the (hydro)fluoropropene with a zinc/chromia catalyst containing 0.1 to 20% by weight of zinc, wherein the (hydro)fluoropropene is selected from the monofluoropropene 1-fluoropropene (CH 3 CH═CHF), the difluoropropenes 1,2-difluoropropene (HFC═CFCH 3 ) and 1,3- difloropropene(HFC═CHCF 2 H), the trifluoropropenes 1,2,3,-trifluoropropene(HFC═CFCH 2 F) and 1,3,3trifluoropropene (HFC═CHCF 2 H), the tetrafluoropropenes 1,3,3,3-tetrafluoropropene (HFC═CHCF 3 ) and 1,2,3,3,tetrafloropropene(HFC═CFCF 2 H),and the pentafloropropene 1,2,3,3,3,-pentafloropropene (HFC═CFCF 3 ).
