    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 preparation of 1,1,1,3,3,3-hexafluoropropane is disclosed. The process involves (a) contacting at least one halopropane of the formula CF3CH2CHyX3-y (where each X is independently F, Cl or Br, and y is 3, 2, or 1) with Cl?2#191 in the presence of light or a free radical initiator to produce a mixture comprising CF3CH2CCIyX3-y; (b) contacting the CF3CH2CCIyX3-y produced in step (a) with HF, optionally in the presence of a fluorination catalyst, to produce a product mixture comprising CF3CH2CF3; and (c) recovering CF3CH2CF3 from the mixture produced in step (b).
