Abstract (1-Benzyl-1H-1,2,3-triazole-4-yl)methanol (BTM) and (1-(pyridin-4-ylmethyl)-1H-1,2,3- triazole-4-yl)methanol (PTM) were prepared and investigated as corrosion inhibitors for mild steel in 1.0 M HCl. It is found that PTM functions as more effective inhibitor than BTM in the concentration range of 0.2 −1.0 mM. Computational chemistry studies show that the triazole derivatives can adsorb on the mild steel surface by sharing the lone pair electrons of N atoms with iron atoms or by accepting electrons from iron surfaces. Due to its strong interaction with the mild steel surface in aqueous system, the pyridine segment should be responsible for the higher inhibition efficiency of PTM.

1,2,3-三唑衍生物作为酸性介质中低碳钢的缓蚀剂：实验和计算化学研究

摘要 (1-Benzyl-1H-1,2,3-triazole-4-yl)甲醇 (BTM) 和 (1-(pyridin-4-ylmethyl)-1H-1,2,3-triazole-4-yl)在 1.0 M HCl 中制备并研究了甲醇 (PTM) 作为低碳钢的缓蚀剂。发现在 0.2 -1.0 mM 的浓度范围内，PTM 作为比 BTM 更有效的抑制剂。计算化学研究表明，三唑衍生物可以通过与铁原子共享 N 原子的孤对电子或从铁表面接受电子来吸附在低碳钢表面。由于其与水性体系中低碳钢表面的强相互作用，吡啶链段应负责 PTM 的更高抑制效率。
