摘要： Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF═CH2 (1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCl2═CClCH2Cl (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 CF3CCl═CH2, preferably in a 80-96% selectivity. The CF3CCl═CH2 is preferably converted to CF3CFClCH3 (244-isomer) using a SbCl5 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 FeCl3/C is preferably used as the catalyst to achieve high selectivity to CF3CCl═CH2 (96%). In the second step, SbCl5/C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CF3CFClCH3. 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%.

摘要： Provided is a method for easily and safely removing, from a reactor, a catalyst used in a reaction that is performed using hydrogen fluoride in the presence of the catalyst. In a reaction performed in a reactor containing at least hydrogen fluoride and a catalyst, the catalyst is removed through a process comprising a heating step of performing heat-treatment so that the ambient temperature of the reactor is 80° C. or more after completion of the reaction, and a purge step of flowing inert gas into the reactor to discharge the hydrogen fluoride to the outside of the reactor after completion of the reaction.
