    摘要: Disclosed is an integrated manufacturing process to co-produce (E)1-chloro-3,3,3-trifluoropropene, (E)1,3,3,3-tetrafluoropropene, and 1,1,1,3,3-pentafluoro-propane starting from a single chlorinated hydrocarbon feed stock, 240fa. The process includes a combined liquid or vapor phase reaction/purification operation which directly produces (E)1-chloro-3,3,3-trifluoropropene (1233zd(E)) from 240fa. In the second liquid phase fluorination reactor 1233zd(E) is contacted with HF in the presence of catalyst to produce 1,1,1,3,3-pentafluoropropane (245fa) with high conversion and selectivity. A third reactor is used for dehydrofluorination of 245fa to produce (E)1,3,3,3-tetrafluoropropene (1234ze(E)) by contacting in the liquid phase with a caustic solution or in the vapor phase using a dehydrofluorination catalyst. This operation may be followed by one or more purification processes to recover the 1234ze(E) product.

    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 1,1,1,3-tetrachloropropene and/or 1,1,3,3-tetrachloropropene 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 by-product HCl); an optionally (2) the 244fa stream can then be used to directly produce any (or all) of the following desired products; (a) the 244fa stream can be dehydrochlorinated to produce the desired second product 1234ze (E); and/or (b) the 244fa stream can be dehydrofluorinated to produce 1233zd (E) if more of that product is desired; and/or (c) the 244fa stream can be further fluorinated to form 245fa.
