Abstract:
The disclosure relates to a method for hydrofluorination of an olefin of the formula: RCX═CYZ to produce a hydrofluoroalkane of formula RCXFCHYZ or RCXHCFYZ, wherein X, Y, and Z are independently the same or different and are selected from the group consisting of H, F, Cl, Br, and C 1 -C 6  alkyl which is partially or fully substituted with chloro or fluoro or bromo; and R is a C 1 -C 6  alkyl which is unsubstituted or substituted with chloro or fluoro or bromo, comprising reacting the olefin with HF in the liquid-phase, in the presence of SbF 5 , at a temperature ranging from about −30° C. to about 65° C. and compositions formed by the process.

Claim (Index 16):
A hydrofluoroalkane composition formed by reacting HF with an olefin comprising at least one member selected from the group consisting of 2-chloro-3,3,3-trifluoropropene, 1-chloro-3,3,3-trifluoropropene, chlorotetrafluoropropenes, 2,3,3,3-tetrafluoropropene, 1,3,3,3-tetrafluoropropene, and 3,3,3-trifluoropropene in the liquid phase in the presence of a catalyst at a temperature ranging from about \u221230\u00b0 C. to about 40\u00b0 C. to produce the hydrofluoroalkane;\n wherein the hydrofluoroalkane composition comprises greater than 95% RCXFCHYZ, wherein X, Y and Z are independently the same or different and are H, F, or Cl, and R is trifluoromethyl.
