Patent ID: 8450537

Claim:
A process for making at least one product compound selected from the group consisting of CF 3 CH 2 CHF 2 , CF 3 CH═CHF and CF 3 CH═CHCl, comprising: reacting at least one starting material selected from the group consisting of halopropenes of the formula CX 3 CH═CH 2 and halopropenes of the formula CX 2 ═CHCH 2 X wherein each X is independently selected from the group consisting of F and Cl, with HF and Cl 2 in a reaction zone, optionally in the presence of a chlorofluorination catalyst, to produce a product mixture comprising HF, HCl, CF 3 CH 2 CHF 2 , CF 3 CH═CHF and CF 3 CH═CHCl, wherein the molar ratio of HF to total amount of starting material fed to the reaction zone is at least stoichiometric and wherein the molar ratio of Cl 2 to total amount of starting material fed to the reaction zone is 2:1 or less; and recovering said at least one product compound from the product mixture.
