Abstract

1,251,899. Electrolytic hydrodimerization of nitriles. ASAHI KASEI KOGYO K.K. 10 Feb., 1969, No. 7033/69. Heading C2C. [Also in Division C7] α,#-Monoolefinically-unsaturated nitriles are electrolytically hydrodimerized, using a leadsilver anode, while hydrogen cyanide is removed from the anolyte. Specified starting materials are acrylonitrile, methacrylonitrile, 2- pentene nitrile, 2 - methylene - valeronitrile, crotononitrile, 2 - methylene - butyronitrile, 2- methylenehexane nitrile, 2,3 - dimethyl-crotononitrile, tiglonitrile, senneconitrile, 2- ethylidene - hexane nitrile, fumaronitrile, itaconitrile, citraconitrile and butyrfumaronitrile. Specified methods of removing hydrogen cyanide are aeration, vacuum deaeration, heat deaeration, ion-exchange, anolyte exchange, oxidative decomposition and hydrolysis. A portion of the anolyte may be withdrawn for aeration or vacuum deaeration. Antimony, tellurium, tin, calcium, copper, cadmium or cobalt may be incorporated into the anode, which may be hardened by quenching. In practice a coating of lead peroxide is formed on the anode.
