摘要
成功合成了含咪唑环不对称双季铵盐,通过失重法、电化学阻抗谱、动电位扫描极化曲线、扫描电镜对合成产物在3%Na Cl的饱和二氧化碳溶液中的缓蚀效率进行研究。结果表明,其在饱和二氧化碳溶液中对钢铁有着良好的缓蚀作用,缓蚀效率接近90%;运用Langmuir吸附等温式对吸附行为进行了拟合,表明其吸附类型符合Langmuir吸附模型,吸附方式为化学吸附。
The asymmetric bis quaternary ammonium salt containing imidazole ring was synthesised suc-cessfully. And weight-loss method,electrochemical impedance spectroscopy,potentiodynamic polarization curve,scanning electron microscopy was used to study on the inhibition efficiency of this product in sodi-um chloride solutions（3. 00%）bubbled with CO2-saturated. The result shows that it has good corrosion inhibition for the P110 steel in this solution,and the corrosion inhibition efficiency is closed to 90%. The adsorption behavior was fitted using the Langmuir adsorption isotherm,and showed that the adsorption type conforms to the Langmuir adsorption isotherm,its adsorption mode is chemical adsorption.
