    摘要: Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF3X1 with a compound of CX2H=CHX3, wherein X1, X2, and X3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF3CH=CHX3, wherein X3 is as described above; and when X3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into -tetrafluoropropene (1,3,3,3-tetrafluoropropene).

    摘要: A process for the catalytic fluorination of hydrochlorocarbons and hydrochlorofluorocarbons in the liquid phase. The process is useful for fluorinating hydrochloropropanes, hydrochlorofluoropropanes, hydrochloropropenes and hydrochlorofluoropropenes and most particularly useful for fluorinating 1,1,1,3,3-pentachloropropane to 1,1,1,3,3-pentafluoropropane. Suitable catalysts include (i) a pentavalent molybdenum halide; (ii) à tetravalent tin halide; (iii) a tetravalent titanium halide; (iv) a mixture of a pentavalent tantalum halide with a tetravalent tin halide; (v) a mixture of a pentavalent tantalum halide with a tetravalent titanium halide; (vi) a mixture of a pentavalent niobium halide with a tetravalent tin halide; (vii) a mixture of a pentavalent niobium halide with a tetravalent titanium halide; (viii) a mixture of a pentavalent antimony halide with a tetravalent tin halide; (ix) a mixture of a pentavalent antimony halide with a tetravalent titanium halide; (x) a mixture of a pentavalent molybdenum halide with a tetravalent tin halide; (xi) a mixture of a pentavalent molybdenum halide with a tetravalent titanium halide and (xii) a mixture of a pentavalent antimony halide with a trivalent antimony halide. Products of this process are useful in a variety of applications including solvents, blowing agents, and refrigerants.
