【摘要】 合成新型的含氯咪唑啉化合物(CIM),以~1H-NMR和FTIR确定其结构,并采用静态失重法、动电位极化曲线、电化学阻抗等方法研究其在0.5mol/L盐酸溶液中的对碳钢腐蚀的抑制表现。结果表明,CIM的缓蚀率随其浓度增大而增大,且在高温时保持高效的缓蚀性能。CIM在碳钢表面的吸附行为符合Langmuir吸附等温式,属于混合型吸附。
【Abstract】 a novel imidazoline compound,2-(2-trichloromethyl-4,5-dihydro-imidazol-1-yl)- ethylamine(CIM) was synthesized in laboratory.The structure of CIM was identified by ~1H-NMR and FTIR.Weight-loss,potentiodynamic polarization,electrochemical impedance spectroscopy(EIS)techniques and scanning electron microscope(SEM) were conducted to investigate the corrosion behavior of mild steel in 0.5 mol/L HC1 solution with or without CIM.The results showed that the inhibition efficiency of CIM increased with the increasing inhibitor concentrations and kept effective at high temperatures.The imidazoline compound is a mixed-type inhibitor whose adsorption behavior onto mild steel surface can be well expressed by Langmuir isotherm equation.
