Three glucose derivatives, namely Ethylenediamine-modified glucose, Tetramethylenediamine-modified glucose, and Hexamethylenediamine-modified glucose with three different carbon chain lengths were synthesized using environmentally benign and low-cost reactants at ambient temperature. The synthesized derivatives were evaluated as inhibitors for mild steel corrosion in 1 M HCl using electrochemical, surface analysis (XPS, AFM and contact angle), as well as computational (DFT) techniques. The obtained results suggest that the synthesized glucose derivatives significantly mitigate the corrosion of mild steel and show a rise in the inhibition efficiency with increasing inhibitor dosage. The inhibitor adsorption obeyed the Langmuir isotherm. The XPS analyses provided an elucidation on the interaction of the inhibitors with the steel substrate. The DFT studies showed that the protonated forms of the inhibitors act more prominently compared to the neutral form. The inhibitor HMG having the alkyl chain with six carbon atoms exhibited the highest inhibition performance of >95% at 22.71 × 10⁻⁵ mol L⁻¹.

在环境温度下使用环境友好的低成本反应物合成了三种具有三个不同碳链长度的葡萄糖衍生物，分别为乙二胺修饰的葡萄糖，四亚甲基二胺修饰的葡萄糖和六亚甲基二胺修饰的葡萄糖。使用电化学，表面分析（XPS，AFM和接触角）以及计算（DFT）技术，将合成的衍生物评估为1 M HCl中低碳钢腐蚀的抑制剂。获得的结果表明，合成的葡萄糖衍生物显着减轻了低碳钢的腐蚀，并且随着抑制剂用量的增加，其抑制效率也有所提高。抑制剂吸附遵循朗缪尔等温线。XPS分析提供了抑制剂与钢基材之间相互作用的解释。DFT研究表明，与中性形式相比，质子化形式的抑制剂作用更为显着。烷基链带有六个碳原子的抑制剂HMG在22.71×10时表现出最高的> 95％抑制性能^-5  mol L ^-1。
