    摘要: A process for the production of 1,1-difluoroethane (HFC-152a) comprises:
    (a) providing a reaction vessel,
    (b) providing in the reaction vessel activated carbon impregnated with a strong Lewis acid fluorination catalyst wherein the strong Lewis acid catalyst is selected from the group consisting of halides of As, Sb, Al, Tl, In, V, Nb, Ta, Ti, Zr and Hf,
    (c) activating the catalyst by passing through the activated carbon impregnated with a strong Lewis acid fluorination catalyst anhydrous hydrogen fluoride gas and chlorine gas,
    (d) contacting, in a vapor state in the reaction vessel containing the activated catalyst, hydrogen fluoride and one or more halogenated hydrocarbons selected from the group consisting of chlorofluoromethane, dichloromethane, 1,1,1-trichloroethane, vinyl chloride, 1,1-dichloroethylene, 1,2-dichloroethylene, 1,2-dichloroethane, and 1,1-dichloroethane for a time and at a temperature to produce a product stream comprising hydrofluorocarbon product(s) corresponding to the chlorinated hydrocarbon reactant(s), and one or more of hydrogen chloride, unreacted chlorinated hydrocarbon fluoride, and
    (e) separating the hydrofluorocarbon product(s) from the product stream.

    摘要: A process for the production of halogenofluorocarbons by fluorinating a halogenated hydrocarbon in a reaction system containing an antimony halide of the general formula: SbClpF5-p [wherein p is 0 to 2], hydrogen fluoride, and the halogenated hydrocarbon serving as the starting material with the molar ratio of the antimony halide to hydrogen fluoride being set in the range of 40/60 to 90/10. According to this process, halogenofluorocarbons (HFC) important as the substitute for CFC or HCFC can be highly selectively and economically produced with decreased corrosion of the reactor.
