    摘要: Processes for the production of chlorinated propenes are provided. The processes proceed through the production of cyclic intermediate that is thereafter readily converted to a desired chloropropane, e.g., via selective pyrolysis. The process may be conducted using starting materials that are readily commercially available and/or that may be reacted safely in standard laboratory equipment so that capital cost savings may be seen. The process does not require the use of catalysts and yet, process conditions less extreme than many conventional processes for the production of chlorinated propenes are suitable, so that raw material and utility cost savings are also possible.

    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.
