    摘要： Halocarbons of the structure CF3CF2CH2X, wherein X is either F or Cl or mixtures thereof prepared by: contacting at least one 2-fluorochloropropane with hydrogen fluoride in a first fluorination step in the gas phase or liquid phase under substantially anhydrous conditions, in the absence of added catalyst to partially fluorinate said 2-fluorochloropropane; contacting said partially fluorinated 2-fluorochloropropane with at least the stoichiometric molar equivalent of hydrogen fluoride under substantially anhydrous conditions, in the presence of at least one fluorination catalyst in a second fluorination step; removing said reaction products from contact with said catalyst, and isolating a substantial yield of at least 1,1,1,2,2,3-hexafluoropropane or 1,1,1,2,2, penta-3-chloropropane, or mixtures thereof, respectively.

    摘要： A process for the manufacture of CF3CH═CF2 and CF3CF═CHF is disclosed. The process involves (a) reacting HF and chlorine and at least one halopropene of the formula CX3CCI═CCIX (where each X is independently F or Cl) to produce a product including both CF3CCI2CF3 and CF3CCIFCCIF2; (b) reacting CF3CCI2CF3 and CF3CCIFCCIF2 produced in (a) with hydrogen to produce a product including both CF3CH2CF3 and CF3CHFCHF2; (c) dehydrofluorinating CF3CH2CF3 and CF3CHFCHF2 produced in (b) to produce a product including both CF3CH═CF2 and CF3CF═CHF; and (d) recovering CF3CH═CF2 and CF3CF═CHF from the product produced in (c). In (a), both CF3CCI2CF3 and CF3CCIFCCIF2 are produced in the presence of a chlorofluorination catalyst consisting of (i) compositions comprising a crystalline alpha-chromium oxide where at least 0.05 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by copper, and (H) compositions of (i) which have been treated with a fluorinating agent.
