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： Processes for the production of chlorinated propanes are provided. The processes comprise catalyzing the chlorination of 1,1,1,3-tetrachloropropane with aluminum chloride, either alone or in combination with ferric chloride. Low intensity conditions are appropriate for the process, e.g., temperatures of from ambient to 100° C. and pressures of from ambient to 200 psig may be used. Even though low intensity conditions are used, the aluminum chloride provides at least 1.5 times greater the conversion rate and/or productivity of 1,1,1,3-tetrachloropropane as compared to ferric chloride when used as a single catalyst under similar processing conditions.

摘要： Processes for the production of chlorinated alkanes are provided. The present processes comprise reacting one or more mono- and/or dichloroalkanes to form tri-, tetra- and/or pentachloroalkanes, with high regioselectivity. In those embodiments wherein a dichloroalkane is desirably utilized, it may advantageously be a vicinal dichloroalkane. Further, only one catalyst is utilized. The present processes make use of sulfuryl chloride as a chlorinating agent, rather than a gaseous chlorinating agent such as chlorine gas. Finally, the process uses lower intensity process conditions than at least some conventional processes, and thus, operating costs are saved.
