Patent ID: 8398882

Claim:
A vapor-phase process for making at least one product compound selected from the group consisting of CF 3 CF 2 CH 3 , CF 3 CF═CH 2 and CF 3 CCl═CH 2 , comprising: reacting a halopropane of the formula CX 3 CHClCH 2 X wherein each X is independently selected from the group consisting of F and Cl, with HF in a reaction zone, optionally in the presence of a fluorination catalyst, to produce a product mixture comprising HF, HCl, CF 3 CF 2 CH 3 , CF 3 CF═CH 2 and CF 3 CCI═CH 2 , wherein the molar ratio of HF to total amount of starting material fed to the reaction zone is from about 10:1 to about 30:1; and recovering said at least one product compound from the product mixture.
