    Abstract: Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX=CXCF3, where X = halogen; and (b) treating CF3CX=CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX=CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX=CHCF3 is greatly reduced or eliminated.

    Abstract: Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF 3 CF=CH 2 (1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCI 2 =CCICH 2 CI (which may be purchased or synthesized from 1,2,3- trichloropropane) is fluorinated (preferably with HF in gas-phase in the presence of a catalyst) to synthesize a compound such as CFaCCl=CH2, preferably in a 80-96% selectivity. The CF 3 CCl=CH 2 is preferably converted to CF 3 CFClCH 3 (244-isomer) using a SbCl 5 as the catalyst which is then transformed selectively to 1234yf, preferably in a gas-phase catalytic reaction using activated carbon as the catalyst. For the first step, a mixture Of Cr2O3 and FeCl 3 /C is preferably used as the catalyst to achieve high selectivity to CF 3 CCl=CH 2 (96%). In the second step, SbCl 5 /C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CF 3 CFClCH 3 . The intermediates are preferably isolated and purified by distillation and used in the next step without further purification, preferably to a purity level of greater than about 95%.
