    摘要: A process is disclosed for making CF3CF2CH3, CF3CF═CH2 and/or CF3CCl═CH2. The process involves reacting at least one starting material selected from the group consisting of halopropanes of the formula CX3CH2CH2X, halopropenes of the formula CX3CH═CH2 and halopropenes of the formula CX2═CHCH2X, wherein each X is independently F or Cl, with HF and Cl2 in a reaction zone to produce a product mixture comprising HF, HCl, CF3CF2CH3, CF3CF═CH2, and CF3CCl═CH2; and recovering the CF3CF2CH3, CF3CF═CH2 and/or CF3CCl═CH2 from the product mixture. Also disclosed is a process for making CF3CH2CHF2, CF3CH═CHF, and/or CF3CH═CHCl. This process involves reacting at least one starting material selected from the group consisting of halopropenes of the formula CX3CH═CH2 and halopropenes of the formula CX2═CHCH2X, wherein each X is independently F or Cl, with HF and Cl2 in a reaction zone to produce a product mixture comprising HF, HCl, CF3CH2CHF2, CF3CH═CHF and CF3CH═CHCl; and recovering the CF3CH2CHF2, CF3CH═CHF, and/or CF3CH═CHCl from the product mixture. The molar ratio of HF to the total amount of starting materials fed to the reaction zone for both of these processes is at least stoichiometric, and the molar ratio of Cl2 to total amount of starting material fed to the reaction zone for both of these processes is 2:1 or less.
