四种三唑化合物的合成及它们在盐酸介质中对碳钢缓蚀性能的研究

本文通过“点击化学”的方法合成了四种1,2,3-三唑化合物(3a, 3b, 4a和4b)，通过IR, ¹H NMR, ¹³C NMR 和 single crystal X-ray 晶体结构衍射分析对化合物进行了表征。通过交流阻抗和动电位扫描极化曲线研究四种化合物在1 mol/L HCl 中对碳钢的缓蚀性能。研究结果表明，四种化合物均可作为高效阳离子缓蚀剂，其中化合物4b的缓蚀效果最好，最高抑制效率可达97％。

Synthesis of Four Triazole Compounds and Their Corrosion Inhibitive Effect on Carbon Steel in Hydrochloric Acid Medium

Four new 1,2,3‐triazoles ( 3a , 3b , 4a and 4b ) have been synthesized selectively via click chemistry approach and characterized by elemental analysis, IR, ¹H NMR, ¹³C NMR and single crystal X‐ray crystallographic analysis. The inhibiting action of these compounds against the corrosion of carbon steel in 1.0 mol/L HCl solution was investigated by electrochemical techniques including polarization and electrochemical impedance spectroscopy (EIS), both results of which indicate that these compounds act as good anodic inhibitors. The electrochemical study also shows that 4b is the best inhibitor among the four compounds in this work and its efficiency increases with concentration. The obtained highest IE (inhibition efficiency) of 4b is around 97%.
