Patent ID: 7872161

Claim:
A process for making CF 3 CF═CH 2 comprising: (i) contacting CHCl 2 CF 2 CF 3 in a reaction zone in the presence of a catalytically effective amount of a dehydrofluorination catalyst to produce CCl 2 ═CFCF 3 ; (ii) contacting CCl 2 ═CFCF 3 formed in (i) with H 2 in a reaction zone in the presence of a catalyst comprising a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof, to produce a product mixture comprising CF 3 CF═CH 2 , wherein the mole ratio of H 2 to CCl 2 ═CFCF 3 fed to the reaction zone is between about 1:1 and about 4:1 and; (iii) recovering CF 3 CF═CH 2 from the product mixture formed in (ii).
