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.
