Abstract
1,204,913. Producing adiponitrile by electrolytic hydrodimerization. ASAHI KASEI KOGYO K.K. 14 June, 1967 [14 June, 1966 (3)], No. 27448/67. Heading C2C. [Also in Division C7] Adiponitrile is produced by the electrolytic hydrodimerization of acrylonitrile by employing as catholyte an aqueous emulsion of acrylonitrile containing an electrolyte salt and an anion polymerization inhibitor present in an amount sufficient to suppress any appreciable electric current induced polymerization of acrylonitrile, both the aqueous and oil phases of the emulsion contacting the cathode and the aqueous phase containing less than 5% by weight dissolved acrylonitrile while the oil phase contains sufficient acrylonitrile to replace in the aqueous phase the acrylonitrile consumed. The electrolyte salts and anion polymerization inhibitors are as defined in Specification 1,204,911, and the process described is substantially as described in that Specification subject only to the difference imposed by the aqueous acrylonitrile solution concentration.
