| 中文摘要: |
| 研究以促进剂M、环己胺、盐酸为原料，次氯酸钠为氧化剂，甲苯为溶剂，两步法合成促进剂CBBS的优化工艺条件。结果表明，在促进剂M/环己胺/盐酸/次氯酸钠物质的量比为2/1/2.3/2.6、氧化反应温度为45 ℃、氧化反应时间为50 min、置换反应时间为60 min的优化工艺条件下，产品收率最高可达到91%以上，产品纯度可达到96%以上。该工艺生产过程简单，原料利用率高，生产成本低，具有显著的经济效益，可以取代以促进剂CBS为主要原料的促进剂CBBS的传统合成工艺。 |
| 英文摘要: |
| The optimum conditions of the two-step synthesis process of accelerator CBBS by using accelerator M，cyclohexamine，hydrochloric acid as raw materials，sodium hypochlorite as oxidant，toluene as solvent were studied. The results showed that when the mole ratio of accelerator M/cyclohexamine/ hydrochloric acid/sodium hypochlorite was 2/1/2.3/2.6，the oxidation reaction temperature was 45 ℃，the oxidation reaction time was 50 min and the displacement reaction time was 60 min，the yield of accelerator CBBS was above 91%，and the purity of accelerator CBBS was more than 96%. This process was simple，the utilization ratio of raw materials was high，the production cost was low，economic benefit was remarkable， and it could replace the traditional synthesis process of accelerator CBBS which used accelerator CBS as the main raw material. |
