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.
Di-t-octyldiazene可以通过在强碱性介质中以65℃-90℃的温度用氯化钠次氯酸钠溶液氧化N,N'-二(正辛基)磺酰胺,用最少量的碳氢化合物或氯化碳氢化合物溶剂进行2至5小时的反应,直到反应完成,从而提高收率、纯度和经济性。在氧化反应中,可以选择使用相转移催化剂或叔丁醇。Di-t-octyldiazene用作乙烯单体的聚合引发剂,以及不饱和聚酯树脂的固化剂。
