Abstract: 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.

Abstract: Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material. 1,1,1,2,2-pentachloropropane produced by the process is subjected to catalytic dehydrochlorination and build-up of the same within the process is avoided.

Abstract: Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstock comprising 1,2,3-trichloropropane and chlorinates the 1,1,2,3-tetrachloropropane generated by the process prior to a dehydrochlorination step. Production of the less desirable pentachloropropane isomer, 1,1,2,3,3-pentachloropropane, is thus minimized. The present processes provide better reaction yield as compared to conventional processes that require dehydrochlorination of 1,1,2,3-tetrachloropropane prior to chlorinating the same. The present process can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, while limiting the production of waste water, thus providing further time and cost savings.

The present processes comprise dehydrochlorinating one or more trichloroalkanes having from 3-6 carbon atoms and vicinal chlorine atoms, followed by a series of sequential chlorination and/or further dehydrochlorination steps. Because the trichloroalkane is first dehydrochlorinated, rather than being first chlorinated, greater specificity to desired tetra- and pentachloroalkanes can be seen.
