ABSTRACT:
Crude 2-methyleneglutaronitrile containing as impurities a metal halide, a trialkylamine, and the trimer or a higher polymer of acrylonitrile can be effectively purified by treating the crude 2-methyleneglutaronitrile with hydrochloric acid, sulfuric acid or nitric acid of a concentration of 1 to 30% by weight and then subjecting the treated methyleneglutaronitrile to vacuum distillation.
