Abstract:
A method for producing 1,1,1,2-tetrafluoropropene and/or 1,1,1,2,3-pentafluoropropene using a single set of four unit operations, the unit operations being (1) hydrogenation of a starting material comprising hexafluoropropene and optionally recycled 1,1,1,2,3-pentafluoropropene; (2) separation of the desired intermediate hydrofluoroalkane, such as 1,1,1,2,3,3-hexafluoropropane and/or 1,1,1,2,3-pentafluoropropane; (3) dehydrofluorination of the intermediate hydrofluoroalkane to produce the desired 1,1,1,2-tetrafluoropropene and/or 1,1,1,2,3-pentafluoropropene, followed by another separation to isolate the desired product and, optionally, recycle of the 1,1,1,2,3-pentafluoropropene.

Claim (Index 1):
A method for producing at least one fluorinated olefin comprising:\n a. hydrogenating a starting material stream comprising at least one alkene according to Formula (I):\n (CX n Y 3\u2212n )(CR 1 a R 2 b ) z CX\u2550CH m X 2\u2212m \u2003\u2003(I) \n \u2003by contacting said starting material with a reducing agent to produce an intermediate product stream comprising at least one alkane according to Formula (II):\n (CX n Y 3\u2212n )(CR 1 a R 2 b ) z CHXCH m+1 X 2\u2212m \u2003\u2003(II) \n \u2003where: \u2003each X is independently Cl, F, I or Br, provided that at least two Xs are F; \u2003each Y is independently H, Cl, F, I or Br; \u2003each R 1  is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; \u2003each R 2  is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; \u2003n is 1, 2 or 3; \u2003a and b are each 0, 1 or 2, provided that a+b=2; \u2003m is 0, 1 or 2; and \u2003z is 0, 1, 2 or 3; b. optionally, separating said intermediate product stream into a plurality of stream, said plurality of intermediate product streams comprising two or more stream selected from the group consisting of a first stream rich in at least a first alkane according to Formula II, a seconds stream rich in at least a second alkane according to Formula II, and an alkane recycle stream; c. dehydrofluorinating at least a portion of said intermediate process stream from step (a) or said plurality of intermediate process streams of step (b) to produce an alkene product stream comprising 1,1,1,2,3-pentafluoropropene and at least one additional alkene having a lower degree of fluorine substitution compared to the degree of fluorination of the compound of formula (I); d. separating at least a portion of said 1,1,1,2,3-pentafluoropropene from said alkene product stream to produce a recycle stream rich in 1,1,1,2,3-pentafluoropropene and a final product stream rich in said additional alkene; and e. introducing said recycle stream at said step (a), wherein at least a portion of said 1,1,1,2,3-pentafluoropropene is hydrogenated to form a portion of said intermediate product stream.
