In this article, we evaluated the inhibitory performance of imidazo[4,5-b] pyridine derivatives namely, 6-bromo-2-(4-chlorophenyl)-3-(prop-2-yn-1-yl)-3H-imidazo[4,5-b]pyridine(SB9a) and 6-bromo-2-(4-chlorophenyl)-3-decyl-3H-imidazo[4,5-b]pyridine (SB14a) against mild steel (MS) corrosion in 1 M HCl using weight Loss from 303 to 333 K, Potentiodynamic Polarization (PDP), Electrochemical Impedance Spectroscopy (EIS), Scanning Electron Microscopy (SEM), energy dispersive X-ray (EDX) analysis, UV–vis spectroscopy and computational approach. The studied inhibitors showed a high inhibition performance since achieving a percentage of 90 % for SB14a and 88 % for SB9a 0.1 mM. PDP indicates that the both derivatives behaved as mixed-type inhibitors. Density functional theory (DFT) and molecular dynamic simulation (MD)) supports the experimental results.

在本文中，我们评估了咪唑并[4,5-b] 吡啶衍生物即 6-溴-2-(4-氯苯基)-3-(prop-2-yn-1-yl)-3H-的抑制性能咪唑并[4,5-b]吡啶(SB9a)和6-溴-2-(4-氯苯基)-3-癸基-3H-咪唑并[4,5-b]吡啶(SB14a)对抗低碳钢(MS)腐蚀在 1 M HCl 中使用从 303 到 333 K 的失重、动电位极化 (PDP)、电化学阻抗谱 (EIS)、扫描电子显微镜 (SEM)、能量色散 X 射线 (EDX) 分析、紫外-可见光谱和计算方法. 所研究的抑制剂显示出高抑制性能，因为 SB14a 的抑制率为 90%，SB9a 0.1 mM 的抑制率为 88%。PDP 表明这两种衍生物都表现为混合型抑制剂。密度泛函理论（DFT）和分子动力学模拟（MD））支持实验结果。
