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.

Abstract: Water is removed from a mixture containing water, CO2 and one or more amines by pervaporation by bringing the mixture into contact with one side of a membrane and removing the water-containing permeate as a vapor from the other side of the membrane.

Abstract: Proposed is an electrolytic method for the production of sodium and aluminium chloride in an electrolytic cell with an aluminium anode and a sodium cathode separated from each other by a sodium-ion-conducting solid electrolyte. In the anode region, molten electrolyte containing essentially sodium tetrachloroaluminate is electrolysed, the aluminium chloride produced being evaporated out of the cell and the sodium produced being tapped off from the cathode region.
