Patent ID: 7285691

Claim:
A process for the manufacture of 1,1,1,3,3,3-hexafluoropropane and at least one compound selected from the group consisting of 1,1,1,2,3,3-hexafluoropropane and 1,1,1,2,3,3,3-heptafluoropropane, comprising: (a) reacting HF, Cl 2 , and at least one halopropene of the formula CX 3 CCl═CX 2 , wherein each X is independently selected from the group consisting of F and Cl, to produce a product comprising CF 3 CCl 2 CF 3 and CF 3 CClFCClF 2 , wherein said CF 3 CCl 2 CF 3 and CF 3 CClFCClF 2 are produced in the presence of a chlorofluorination catalyst comprising at least one composition selected from the group consisting of (i) compositions comprising ZnCr 2 O 4 and crystalline α-chromium oxide, (ii) compositions comprising a zinc halide and α-chromium oxide and (iii) compositions of (i) or (ii) which have been treated with a fluorinating agent; (b) reacting CF 3 CCl 2 CF 3 and CF 3 CClFCClF 2 produced in (a) with hydrogen, optionally in the presence of HF, to produce a product comprising CF 3 CH 2 CF 3 and at least one compound selected from the group consisting of CHF 2 CHFCF 3 , and CF 3 CHFCF 3 ; and (c) recovering from the product produced in (b), CF 3 CH 2 CF 3 and at least one compound selected from the group consisting of CHF 2 CHFCF 3 and CF 3 CHFCF 3 .
