1. A composition comprising:
a mixture comprising HF, SbF5, olefin, and a hydrofluoroalkane;
wherein the olefin and the hydrofluoroalkane are selected from:
a) the olefin is (Z)-1-chloro-3,3,3-trifluoropropene or (E)-1-chloro-3,3,3-trifluoropropene and the hydrofluoroalkane is 3-chloro-1,1,13-tetrafluoropropane;
b) the olefin is 1-chloro-2,3,3,3-tetrafluoropropene and the hydrofluoroalkane is 1,1,1,2,2-pentafluoro-3-chloropropane and 1,1,1,2,3-pentafluoro-3-chloropropane;
c) the olefin is 2,3,3,3-tetrafluoropropene and the hydrofluoroalkane is 1,1,1,2,2-pentafluoropropane; and
d) the olefin is 1,3,3,3-tetrafluoropropene and the hydrofluoroalkane is 1,1,1,3,3-pentafluoropropane; and
wherein the SbF5 is present in an amount in the range of about 2% to about 30%, by weight of the mixture.
