Synthesis of dichlorobenzidine hydrochloride using an ion exchange membrane

WANG Ya-dan WANG Qi-nan LI Pei-jin(College of Materials Science and Engineering,Beijing University of Chemical Technology,Beijing 100029,China)  
3,3'-dichlorobenzidine hydrochloride was synthesized by using an ion exchange membrane.Some factors affecting current efficiency and yield are discussed.It was found that the optimum reaction temperature is 80?℃;When the electrolyte concentration was 30% at the anode and 10% at the cathode,the current efficiency reached 93% and yield was 90%.Furthermore,comparable results could be attained when using the recycled electrolyte.
