Abstract: PROBLEM TO BE SOLVED: To electrochemically reduce an org. compd. in a high space-time yield by bringing the org. compd. into contact with a conductive substrate and a cathode having a conductive polarized layer formed formed on the substrate by deposition. SOLUTION: Adiponitrile is reduced to hexamethylenediamine in a split electrolytic cell divided into a cathode compartment and an anode compartment with a cation-exchange membrane as a separation medium. In this case, a filter plate covered with the longitudinally diagonal woven fabric of steel alloy is used sa the cathode, a Ti plate coated with a Ta-Ir mixed oxide is used as the anode, and 2% sulfuric acid is employed as the anolyte, and the mixture of methanol, water, NaOH, adiponitrile and Raney nickel as the catholyte. Raney nickel is previously deposited on a cathode and then electrolytically reduced at 30-40 deg.C and 1000A/m current density. NaOH is removed by electrolysis, and the product is separated by distillation to recover hexamethylenediamine.
