1. from the initial combination producing of 1,1,1,3,3-pentachloropropane (HCC-240fa) (E) 1-chloro-3,3,3-trifluoro propene, (E) 1,3,3, the integrated production method of 3-tetrafluoeopropene and 1,1,1,3,3-pentafluoropropane comprises the following steps:

  • (a) in first reactor, that carries out HCC-240fa fluoridizes to produce (E) 1-chloro-3,3,3-trifluoro propene (1233zd (E));

    (b) in second reactor, that carries out 1233zd (E) fluoridizes to produce 1,1,1,3,3-pentafluoropropane (245fa);

    And randomly,(c) in the 3rd reactor, carry out the dehydrofluorination of 245fa to produce (E) 1,3,3,3-tetrafluoeopropene (1234ze (E)).
