用量子化学半经验计算方法CNDO/2程序,研究了苯胺类缓蚀剂的电子性质与缓蚀性能的关系。结果表明质子化的胺基是苯胺衍生物与金属作用的活性部位。提出了该类分子作为酸性介质中金属缓蚀剂在铁表面形成吸附膜的作用机理。
The correlation of electronic structure to corrosion inhibition properties of aniline derivatives was studied in terms of semi-empirical quantum chemistry calculation. The results showed the protenated amino species of the p-substituted anlines to be the active part which could combine with metal. A mechanism of inhibition was suggested in which the p-substituted anilines, as inhibitor of iron in acidic medium, formed a film on the iron surface.
