硫化促进剂NS合成技术与工艺进展

for Vulcanization Accelerator NS

N－叔丁基－2－苯并噻唑次磺酰胺（NS）是目前发现的综合性能最好、发展速度最快的环保硫化促进剂。本文详尽地介绍了次氯酸钠氧化法、过氧化氢氧化法、催化氧化法、电解氧化法、氯气氧化法合成原理、工艺现状、各工艺路线的优点和存在的问题。其中次氯酸钠氧化法是唯一工业化的技术路线，但有很大环境问题，而等离子氧化法的绿色生产技术将带来NS生产及其它氧化反应生产的颠覆性革命。

N- tert- butyl- 2- benzothiazole- sulfenamide （NS） as a green ~tlcanization accelerator has the best comprehensive performance and the fastest growing. The paper introduced sodium hypochlorite oxidation, hydrogen peroxide oxidation, catalytic oxida- tion, electrolytic oxidation, and chlorine oxidation in detail. And the reaction mechanism, status of the process, the advantages of the process, and the existing problems were described. In these methods, sodium hypochlorite oxidation is the only method to achieve indus- trialization, but there are large environmental problems. The green production technology of the ion oxidation will bring NS production and other oxidation reaction production subversive revolutionary.
