ABSTRACT:
A ketazine is reacted with hydrogen cyanide in the presence of at least one salt of a metal selected from the group consisting of zinc, tin, iron, copper, aluminum, antimony, tellurium and bismuth, whereby a hydrazo compound is formed. This hydrazo compound is oxidized with a halogen or the like to obtain an azonitrile. The thus obtained azonitrile is useful as a radical polymerization initiator, photo-polymerization initiator, blowing agent or the like.
