ABSTRACT:
A process for the preparation of 2,2'-azobis(isobutyronitrile) of improved color which comprises reacting 2-amino-2-methylpropionitrile with a metal hypochlorite, M(OCl).sub.x where M is selected from sodium, potassium or calcium and x is the valence of M, in the presence of water and a mixture of a quaternary ammonium surface active compound with either a nonionic or amphoteric surface active compound, said mixture having an HLB of about 8 to about 35 at a temperature of about -10.degree. C to about 30.degree. C and recovering the self-precipitated 2,2'-azobis(isobutyronitrile) from the reaction mixture.
