Abstract

Hydrogen cyanide and hydrogen, and possibly carbon, are produced from the reaction in an enclosed electric are of ammonia and one or more hydrocarbons, containing 1-4 carbon atoms and not more than one olefinic bond. The reaction time is 0.00002-0.001 seconds and the reaction products are rapidly cooled. The hydrogen cyanide is separated by washing, preferably with sodium hydroxide to give the cyanide.
