Use of gas depolarized anodes for the electrochemical production of adiponitrile

Gas depolarized anodes used in the electrohydrodimerization of acrylonitrile to adiponitrile result in anode voltage requirements of less than about 400 millivolts at 100 milliamperes per square centimeter of electrode area. Typically, oxygen evolving anodes characterized by high theoretical voltage...

Summary:Gas depolarized anodes used in the electrohydrodimerization of acrylonitrile to adiponitrile result in anode voltage requirements of less than about 400 millivolts at 100 milliamperes per square centimeter of electrode area. Typically, oxygen evolving anodes characterized by high theoretical voltages and high overvoltages are utilized in the hydrodimerization of acrylonitrile to adiponitrile. Gas depolarized anodes requiring substantially reduced voltages perform well in the conventional electrochemical adiponitrile production environment.
