2-巯基苯并噻唑季铵盐型复配水处理剂的合成及性能研究

Study of synthesis and properties of quaternary ammonium salt type compound water treatment agent of 2-mercaptobenzothiazole

为减少工业水处理剂的污染问题,采用2-巯基苯并噻唑为原料,通过巯基烷基化与水溶性的季铵基团结合,合成了3种带有季铵基团的苯并噻唑衍生物,并证实了它们的结构。缓蚀性能实验和杀菌实验表明氯化二甲基苄基[2-(2-苯并噻唑基硫代)乙基]铵的性能为最佳。

Abastract：In order to reduce the pollution of industrial water treatment agent,in this paper,three new ben-zothiazole derivatives with quaternary ammonium group were synthesized,and the structures were confirmed,through the mercaptoalkyl of quaternary ammonium groups.The corrosion inhibition performance experiment and the sterilization experiment showed that the performances of two methyl benzyl chloride [2-（2-benzothiazolyl thio）ethyl] ammonium were the best.
