Integrated HFC trans-1234ze manufacture process

摘要

An integrated process for the manufacture of HFO trans-1,3,3,3-tetrafluoropropene (HFO trans-1234ze) by first catalytically dehydrofluorinating 1,1,1,3,3-pentafluoropropane to thereby produce a mixture ofcis-1.3,3,3-tetrafluoropropene, trans-1.3.3,3-tetrafluoropropene and hydrogen fluoride. Then optionally recovering hydrogen fluoride, catalytically isomerizing cis-1234ze into trans- 1234ze, and recovering trans-1,3,3,3-tetrafluoropropene.
