    摘要： 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 CFaCCI=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, SbCls/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%.

    摘要： Disclosed is process for the production of (E) 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) by conducting a continuous reaction without the use of a catalyst. Also disclosed is an integrated system for producing hydrofluoro olefins, particularly 1233zd(E). The manufacturing process includes six major unit operations: (1) a fluorination reaction of HCC-240fa (in continuous or semi-batch mode) using HF with simultaneous removal of by-product HCl and the product 1233zd(E); (2) recycle of unreacted HCC-240fa and HF together with under-fluorinated by-products back to (1); (3) separation and purification of by-product HCl; (4) separation of excess HF back to (1); (5) purification of final product, 1233zd(E); and (6) isomerization of by-product 1233zd(Z) to 1233zd(E) to maximize the process yield.
