Abstract

Electrochemical dechlorination of chlorobenzene in organic solutions was studied. Electrolysis of chlorobenzene in acetonitrile solution in a one-compartment cell fitted with a platinum cathode and a zinc anode at 60 mA/cm2 and 0°C was found to be the optimum conditions, which gave complete dechlorination. However, similar result could not be achieved when applying this condition to 1,3-dichlorobenzene and 1,2,4- trichlorobenzene. We found that the use of naphthalene which reacts as a mediator in the system could accelerates the reduction and gave complete dechlorination of those chlorobenzenes. Moreover, in the presence of naphthalene the reaction time could be shortened by half compare to the dechlorination in the absence of naphthalene.
