Abstract

PURPOSE: To obtain a high purity compound of azonitrile, which is a foaming agent and a radical initiator, by the treatment of a reaction mixture, obtained by the oxidative coupling reaction of aminonitrile and a metal salt of hypohalous acid, with a specific reducing agent.
CONSTITUTION: An azonitrile compound is obtained by the reaction of aminonitrile and a metal salt of hypohalous acid in a heterogeneous solvent comprising a water phase and an organic phase in the presence of a catalyst, e.g. organic quaternary ammonium salt, wherein the reaction mixture obtained by the oxidative coupling reaction is treated with a reducing agent, e.g. nitrite, sulfur dioxide, hydrazine etc. The oily impurities can be decomposed by the treatment, and the compound can be readily crystallized.
