摘　　要：研究以促进剂M和叔丁胺为原料,过氧化氢为氧化剂,CuA_2/MnA_2(A为有机酸根或配体)双金属有机酸盐为催化剂合成橡胶促进剂NS的优化工艺条件。结果表明,在促进剂M/叔丁胺/过氧化氢物质的量比为1/(3~4)/(1.5~2)、催化剂CuA_2/MnA_2物质的量比为10/1、催化剂质量为促进剂M质量的1%、反应温度为50~70℃、反应时间为60 min的优化工艺条件下,促进剂NS合成反应效果最优,产品收率最高可达96%以上。The optimum conditions for the synthesis of rubber accelerator NS were studied by using the accelerator M and tert-butylamine as raw materials,hydrogen peroxide as oxidant and metallic organic acid salts CuA2/MnA2（A was organic acid or ligand） as a catalyst.The results showed that when the ratio of accelerator M/tert-butylamine/hydrogen peroxide was 1/（3～4）/（1.5～2）,the ratio of catalyst CuA2/MnA2 was 10/1,the catalyst amount was 1% of the weight of accelerator M,the reaction temperature was 50～70 ℃ and the reaction time was 60 min,the yield of accelerator NS was the best and it was above 96%.
