    Abstract: 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.

    Abstract: The present invention discloses high purity E-1-chloro-3,3,3-trifluoropropene (1233zd(E)) and methods to produce the same. More specifically, the present invention discloses the methods of making 1233zd(E) essentially free of toxic impurities (e.g. 2-chloro-3,3,3-trifluoropropene (1233xf), chlorotetrafluoro-propene (1224), and 3,3,3-trifluoropropyne). The present invention further provides methods for making high purity 1233zd(E) with concentration of 1233xf and 1224 at or below 200 parts per million (ppm) and 3,3,3-trifluoropropyne impurities at or below 20 ppm. Formation of 1233xf impurity can be avoided if pure 1,1,1,3,3-pentachloropropane is used as a starting material. It was also found that formation of 1233xf is avoided if a liquid phase manufacturing process is used.
