<P>PROBLEM TO BE SOLVED: To provide a method for producing integrated HFC trans-1234ZE. <P>SOLUTION: The integration method for the production of HFO trans-1,3,3,3-tetrafluoropropene (HFO trans-1234ze) comprises the catalytic dehydrofluorination of 1,1,1,3,3-pentafluoropropane to obtain a mixture of cis-1,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and hydrogen fluoride. After the production, optionally the hydrogen fluoride is recovered, cis-1234ze is converted to trans-1234ze by catalytic isomerization and the obtained trans-1,3,3,3-tetrafluoropropene is recovered. <P>COPYRIGHT: (C)2008,JPO&INPIT |
