| 中文摘要: |
| 研究以促进剂M和叔丁胺为原料，过氧化氢为氧化剂，CuA2/MnA2（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CuA2/MnA2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。 |
| 英文摘要: |
| 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%. |
