ABSTRACT:
A method for producing adiponitrile through the electrohydrodimerization of acrylonitrile by electrolyzing an emulsion comprised of an aqueous phase and an organic phase in at least one undivided cell having a cathode of lead or a lead alloy, in which an ethyltributylammonium salt as a quaternary ammonium salt is included in the aqueous phase in a concentration of from 0.02 to 0.08 mol/liter. The method of the present invention is remarkably improved with respect to the prevention of the corrosion of the cathode.
