ABSTRACT:
This invention relates a process for the manufacture of the HFO trans-1,3,3,3-tetrafluoropropene (HFO trans-1234ze). More particularly, the invention pertains to a process for the manufacture of the HFO trans-1234ze by first dehydrofluorinating 1,1,1,3,3-pentafluoropropane to thereby produce a mixture of cis-1,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and hydrogen fluoride. Then optionally recovering hydrogen fluoride and then recovering trans-1,3,3,3-tetrafluoropropene.
