Patent ID: 8053611

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, hexafluoropropene 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═CClX, 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 chromium-containing component selected from (i) a crystalline alpha-chromium oxide where at least 0.05 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by divalent copper, and (ii) a chromium-containing composition of (i) which has 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 , CF 3 CF═CF 2 and CF 3 CFHCF 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 , CF 3 CF═CF 2 and CF 3 CFHCF 3 .
