摘　　要：以N-甲基苯胺、二硫化碳为原料,水为溶剂,双氧水为氧化剂,用Py-De为催化剂合成N,N-二甲基-N,N-二苯基秋兰姆二硫化物。考察了原料的溶剂用量及种类、反应温度、反应时间等对收率、纯度的影响。实验结果表明:最优物料的配比为n(N-甲基苯胺)∶n(二硫化碳)∶n(双氧水)=1∶1.02∶0.55。加成反应最佳温度10~15℃,氧化反应最佳温度10~15℃,最佳催化剂Py-De,双氧水浓度为8%,双氧水滴加时间为7 h。Using N-methylaniline and carbon disulfide as raw materials,water as solvent,hydrogen peroxide as oxidant,Py-De as catalyst,N,N-dimethyl-N,N-diphenylqiuram disulfides is synthesized.The effects of solvent amount and type of raw materials,reaction temperature and reaction time on yield and purity are investigated.Experimental results show that,the optimal molar ratio of materials is n(N-methylaniline)∶n(Carbon disulfide)∶n(hydrogen peroxide)=1∶1.02∶0.55.Optimum reaction temperature for addition reaction is 10~15℃,the best reaction temperature of oxidation reaction is 10~15℃.Best catalyst is Py-De.Hydrogen peroxide concentration is 8%.The dropping time of hydrogen peroxide is 7 h.
