Abstract: 1,137,544. Electrolytic hydrodimerization of acrylonitrile. BADISCHE ANILIN- & SODA FABRIK A.G. 13 April, 1966 [14 April, 1965], No. 16133/66. Heading C2C. [Also in Division C7] Adiponitrile is produced electrolytically by hydrodimerizing acrylonitrile as catholyte in a cell wherein the anolyte and catholyte are separated by a solid polyelectrolyte which directly covers either or both of the opposed faces of the two electrodes, or joins together the anode and cathode, leaving no interspace between the electrode and polyelectrolyte, the or each covered electrode being permeable to the anolyte and/or catholyte. The catholyte or anloyte may contain a conducting salt solution or water; an acid and/or a base may be added to the anolyte. The polyelectrolyte may be a copolymer layer, e.g. of (dimethyl) styrene and divinylbenzene, phenyl-formaldehyde resins or vinyl chloride containing sulphonic or carboxylic or arsenic acid, phosphonium, ammonium, phosphine, hydroxyl or amino groups; or particles of inorganic ion exchanger, e.g. hydrated zirconium oxides, glauconite, zeolite (hydroxy) apatite, distributed in a binder, e.g. polystyrene, polybutadiene, polyisoprene or cement. The anode may be a porous sintered graphite tube surrounded first by the copolymer layer then by the cathode, e.g. of amalgamated silver netting, the catholyte being acrylonitrile and tetraethyl ammonium p-toluene-sulphonate solution, and the anolyte pure water. The anode may also be of a platinum group metal, lead, lead dioxide, sintered nickel, nickel coated with nickel sulphide or arsenide, or magnetite, and may be vibrated; the cathode may also be of lead, lead amalgams or alloys.
