【摘要】 合成了一种新型三唑衍生物:苯戊酮-O-1-(1.3.4-三氮唑)亚甲基肟(POTM),通过失重试验、交流阻抗、动电位极化研究了其在酸性介质中的缓蚀效率,并用扫描电镜方法观察了碳钢表面的腐蚀形貌。对热力学参数进行了讨论,表明化合物在碳钢表面上的吸附行为服从Langmuir吸附等温式。同时用量子化学中的从头算方法对缓蚀剂的分子结构与缓蚀性能的关系进行了研究。更多还原

【Abstract】 Pentanophenone-O-1-(1.3.4-triazolyl)-metheneoxime(POTM) has been synthesized as a new corrosion inhibitor of mild steel in acid media.The inhibition efficiency was evaluated by means of weight loss,electrochemical impedance spectroscopy(EIS) and polarization curves.The surface morphology was studied by scanning electron microscopy(SEM).The thermodynamic parameters were determined and discussed.The relationship between molecular structure of the compound and the inhibition efficiency was investigated by ab initio quantum chemistry calculations.The adsorption of triazole derivatives was found to obey Langmuir adsorption isotherm.更多还原
