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 CCl 2 ═CClCH 2 Cl (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 CF 3 CCl═CH 2 , 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 Cr 2 O 3  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%.
