促进剂NS合成工艺研究

采用促进剂M-Na盐作原料,加入少量的SDS作分散剂,同时将配制稀释的叔丁胺溶液投料,以次氯酸钠作氧化剂,合成硫化促进剂NS。实验最佳条件：主要原料配比：n（M）：n（NaOH）：n（叔丁胺）为1：1.02：2.6,分散剂SDS用量为M质量的0.4%。产品NS的一级品率达到90%以上,得率最大达到93.62%。

Synthesis Techniques of Rubber Accelerator NS

A process was described in this paper production of rubber accelerator NS, with M-Na salt as feedstock, a small amount of SDS as dispersant,sodium hypochlorite as oxidant, in the dilute solution of tert-butyl- amine. A preferred reaction condition would be a molar ratio of NaOH to tert-butylamine as 1:1.02:2.6, with the amount of dispersant SDS as 0.4% of M. The best-grade product NS get thereby reached above 90%, with a maximized yield of 93.62%.
