Abstract

A novel Schiff base, 2-[(4-thiazolylamino) methyl] phenol (TAMP), was synthesized via microwave-assisted condensation of salicylaldehyde and 4-thiazolamine. The compound was characterized spectroscopically and evaluated as a corrosion inhibitor for carbon steel in 1.0 M HCl. Multiple tests were carried out to evaluate the inhibitor's efficacy. Hence, electrochemical and weight loss analyses demonstrated concentration-dependent inhibition efficiency, reaching 77.4 % at 500 mg/L. In addition, SEM confirmed protective film formation via adsorption on the steel surface. Furthermore, theoretical studies (DFT/MD simulations) elucidated the adsorption mechanism at the metal/electrolyte interface, revealing synergistic protonation and planar orientation as key factors enabling high surface coverage (89 %) and charge transfer.

新型希夫碱绿色缓蚀剂在1 M盐酸中对低碳钢的制备及评价

以水杨醛和4-噻唑胺为原料，微波缩合合成了新型希夫碱2-[（4-噻唑胺）甲基]苯酚（TAMP）。对该化合物进行了光谱表征，并在1.0 M HCl中对碳钢进行了缓蚀剂评价。进行了多项试验来评价该抑制剂的疗效。因此，电化学和失重分析证明了浓度依赖性的抑制效率，在500mg /L时达到77.4%。此外，扫描电镜证实了钢表面通过吸附形成保护膜。此外，理论研究（DFT/MD模拟）阐明了金属/电解质界面的吸附机理，揭示了协同质子化和平面取向是实现高表面覆盖率（89%）和电荷转移的关键因素。
