A process is disclosed 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 is at least stoichiometric, and the molar ratio of Cl2 to total amount of starting material fed to the reaction zone is 2:1 or less.
