Abstract

A natural amino acid methionine-derived imidazole zwitterion was synthesized and investigated as a corrosion inhibitor on cold-rolled steel in an acid environment using weight loss, electrochemistry, and SEM techniques. The synthesized imidazole zwitterion inhibitor was fulfilled with green parameters: multicomponent single-step reaction, reaction at ambient temperature, and water used as a solvent. The corrosion study results show that imidazole zwitterion exhibits effective inhibition efficiency (84 %) at very low concentrations (100 ppm). The imidazole zwitterion exhibited excellent inhibition efficiency (72 %) at high temperature (95 °C). SEM results supported the experimental findings. The adsorption of imidazole zwitterion obeys the Langmuir adsorption isotherm with a uniform inhibitor film achieved via physical and chemical adsorption mechanisms. Imidazole zwitterion can be useful in low inhibitor concentration applications such as pipeline flushing and cleaning.

氨基酸衍生咪唑两性离子作为冷轧钢绿色界面缓蚀剂

合成了一种天然氨基酸甲硫氨酸衍生的咪唑两性离子，并利用失重、电化学和扫描电镜技术在酸性环境下研究了咪唑两性离子对冷轧钢的缓蚀剂作用。合成的咪唑两性离子抑制剂符合绿色参数：多组分单步反应、常温反应、水为溶剂。研究结果表明，咪唑两性离子在极低浓度（100 ppm）下具有良好的缓蚀效果（84%）。咪唑两性离子在95℃高温下具有良好的抑菌效果（72%）。SEM结果与实验结果一致。咪唑两性离子的吸附遵循Langmuir吸附等温线，通过物理和化学吸附机制形成均匀的抑制剂膜。咪唑两性离子可用于低抑制剂浓度的应用，如管道冲洗和清洗。
