Patent ID: 7285692

Claim:
A process for the manufacture of 1,1,1,3,3-pentafluoropropane and 1,1,1,2,3-pentafluoropropane, comprising: (a) reacting hydrogen fluoride, chlorine, and at least one halopropene of the formula CX 3 CCl═CClX, wherein each X is independently selected from the group consisting of F and Cl, to produce a product comprising CF 3 CCl 2 CClF 2 and CF 3 CClFCCl 2 F, wherein said CF 3 CCl 2 CClF 2 and CF 3 CClFCCl 2 F 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 CClF 2 and CF 3 CClFCCl 2 F produced in (a) with hydrogen to produce a product comprising CF 3 CH 2 CHF 2 and CF 3 CHFCH 2 F; and (c) recovering CF 3 CH 2 CHF 2 and CF 3 CHFCH 2 F from the product produced in (b).
