INTEGRATED PROCESS TO CO-PRODUCE TRANS-1-CHLORO-3,3,3-TRIFLUOROPROPENE, TRANS-1,3,3,3-TETRAFLUOROPROPENE, AND 1,1,1,3,3-PENTAFLUOROPROPANE |
摘要 |
Disclosed is an integrated process to co-produce trans-1-chloro-3,3,3-trifluoro- propene (1233zd(E)), trans-1,3,3,3-tetrafluoropropene (1234ze(E)), and 1,1,1,3,3- pentafluoropropane (245fa). Overall the co-production is a three-step process. The chemistry involves the steps of: (1) the reaction of 240fa with anhydrous HF in excess in a liquid-phase catalyzed reactor in such a way as to co-produce primarily 1233zd(E) and 244fa (plus byproduct HC1); (2) the 244fa stream can then be used to directly produce any of the three desired products; (3 a) the 244fa stream can be dehydrochlorinated to produce the desired second product 1234ze(E); and/or (3b) the 244fa stream can be dehydrofluorinated to produce 1233zd(E) if more of that product is desired; and/or (3 c) the 244fa stream can be further fluorinated to form 245 fa. |
