ABSTRACT:
Di-t-octyldiazene is prepared in improved yield, purity and economics by oxidizing N,N'-di-t-octylsulfamide with sodium hypochlorite solution in a strongly basic medium at a temperature of 65.degree.-90.degree. C. in a minimal amount of hydrocarbon or chlorinated hydrocarbon solvent for about 2 to 5 hours until completion of the reaction. The employment of phase transfer catalysts or t-butyl alcohol in the oxidation is optional. Di-t-octyldiazene is used as a polymerization initiator for vinyl monomers and as a curing agent for unsaturated polyester resins.
