Abstract
An improvement in the process of electrohydrodimerizing acrylonitrile to adiponitrile wherein cadmium-plated cathodes, which are employed in the process as a part of an electrolytic cell, are pretreated by contacting the cathode surface with an oxidizing agent comprising peroxide.
Claims7
In an electrochemical process for hydrodimerization of acrglonitrile which comprises electrolyzing in a reaction cell an aqueous electrolyte solution, the aqueous electrolyte solution being in contact with a cadmium cathode surface, the improvement comprising contacting the cathode surface with an oxidizing agent comprising acidic hydrogen peroxide before electrolyzing the aqueous electrolyte solution.
