ABSTRACT:
A process for the preparation of 2,2'-azobis(2,4-dimethyl-4-methoxypentanenitrile) in improved yields with improved filtering characteristics, said process comprising reacting 2-amino-2,4-dimethyl-4-methoxypentanenitrile with a metal hypochlorite in the presence of water, a quaternary ammonium surface active compound and ionic bromide wherein the equivalent ratio of ionic bromide to surface active compound is 0.4:1-4:1 at a temperature of about -10.degree. C. to about 30.degree. C., and recovering 2,2'-azobis(2,4-dimethyl-4-methoxypentanenitrile) from the reaction mixture.
