    摘要: Processes for the production of chlorinated propenes are provided. The processes make use of 1,2-dichloropropane as a starting material and subject a feedstream comprising the same to an ionic chlorination process. At least a portion of any tri- and tetrachlorinated propanes not amenable to ionic chlorination conditions are removed from the ionic chlorination product stream, or, are subjected to chemical base dehydrochlorination step. In this way, recycle of intermediates not amenable to ionic chlorination reactions is reduced or avoided, as is the buildup of these intermediates within the process. Selectivity and, in some embodiments, yield of the process is thus enhanced.

    摘要: Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The processes are conducted in a nonaqueous media, and so, the one or more inorganic iodine salts are recoverable and/or reusable, in whole or in part.

    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 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%.
