Abstract

Carboxyethylthiosuccinic acid (CETSA) was synthesized by thiol-ene click reaction and determined by various characterization methods, such as ¹H NMR, IR and TG. A novel rust remover with corrosion inhibition was prepared by using CETSA as the main component. The results of rust removal were tested by the difference method and intuitive comparison method, and its rust removal mechanism was explored. The corrosion inhibition effect of the composite reagent for A3 steel in 1 M HCl solution was investigated by static weight loss test, the adsorption isotherm was calculated and fitted.

硫醇-烯点击反应合成羧乙基硫代琥珀酸：一种具有缓蚀性能的新型除锈剂

摘要

通过硫醇-烯点击反应合成羧乙基硫代琥珀酸（CETSA），并通过各种表征方法（例如¹ H NMR，IR和TG）进行测定。以CETSA为主要成分，制备了一种新型的缓蚀除锈剂。采用差值法和直观比对法对除锈效果进行了测试，探讨了除锈机理。通过静态失重试验研究了A3钢复合试剂在1 M HCl溶液中的缓蚀作用，计算并拟合了吸附等温线。

图形摘要

CETSA合成为新型除锈剂，可通过渗透和螯合去除金属表面的锈。它具有出色的除锈性能，并通过形成吸附膜来保护金属免受腐蚀。
