ABSTRACT:
The invention relates to a process for preparing hydrofluorocarbons of the formulas CF.sub.3 (CH.sub.2 CF.sub.2).sub.n F comprising reacting at least one reactant selected from CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.n Cl, CCl.sub.3 (CH.sub.2 CF.sub.2).sub.n Cl or CCl.sub.2 [(CH.sub.2 CF.sub.2)Cl].sub.2, where n=1 to 3, with hydrogen fluoride at a temperature of from about 25.degree. to about 200.degree. C.
