Patent ID: 7078575

Claim:
A process comprising combining in a pressure vessel an olefin represented by the Structure I wherein R f is a fluorinated alkyl of 1–10 carbons that is linear, branched, or cyclic; R′ is H, F, an alkyl of 1–6 carbons that is linear, branched, or cyclic, or a fluorinated alkyl of 1–6 carbons that is linear, branched, or cyclic; each R″ is independently H or F, n=0 or 1, and m=1 or 2 provided that m is not 2 when n=0; and a hydrogenation catalyst; sealing the vessel; removing water vapor and air; pressurizing the vessel with hydrogen to a pressure in the range of 10 to 1000 psig; heating the vessel to a temperature from room temperature to 200° C.; allowing the resulting reaction to proceed for 1 to 8 hours to form a reaction product; contacting said reaction product with sulfuric acid or oleum to form an acid treated reaction product; and, contacting said acid treated reaction product with silica gel.
