    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.

There is a second process for making 2-chloro-1,1,1,2-tetrafluoropropane. The process has the step of hydrofluorinating about 75 to about 99.9 mole percent 2-chloro-3,3,3-trifluoropropene and about 0.1 to about 25 mole percent of one or more other hydrocarbons having at least one chlorine atom in the presence of a catalyst of fluorinated antimony pentachloride under conditions sufficient to form the 2-chloro-1,1,1,2-tetrafluoropropane. There is yet another process for hydrofluorinating 2-chloro-3,3,3-trifluoropropene to 2-chloro-1,1,1,2-tetrafluoropropane.
