Abstract

333,989. Imperial Chemical Industries, Ltd., and Wheeler, T. S. June 14, 1929. Aliphatic nitriles are produced by reacting a metal cyanide and an aliphatic halide in the presence of a nitrile, preferably of that nitrile to be produced. In an example, sodium cyanide, ethylene chloride and ethylene cyanide are heated together under a reflux condenser.
