| 摘 要： | 本文采用季铵化试剂与喹啉反应,合成了6种季铵盐型缓蚀剂.通过失重法对它们的缓蚀性能进行了评价,分析了缓蚀剂浓度、腐蚀温度对缓蚀性能的影响,并通过Tafel曲线争EIS谱研究了这些缓蚀剂的缓蚀机理.实验结果表明,6种合成缓释剂的缓蚀效果按从小到大顺序排列为:1,3-二氯化喹啉-2-羟基丙烷＜环氧丙烷基氯化喹啉＜1,2-二溴化喹啉乙烷＜烯丙基氯化喹啉＜(4-乙烯基)-苄基氯化喹啉＜苄基氯化喹啉；当苄基氯化喹啉质量分数为0.1％时,腐蚀电流密度由空白时的222.80μA/cm2降为17.28μA/cm2,缓蚀效率迭92.24％；随缓蚀剂浓度增加,缓蚀效果增强；随温度增加,缓蚀效果减弱.合成缓蚀剂的缓蚀机理均属于“负催化效应”,均为以抑制阳极反应为主的混合型缓蚀剂.对于季铵盐型缓蚀剂,缓蚀剂分子的空间位阻越小,分子中能与Fe原子形成配位键的基团越多,且形成配位键的基团亲水性越差,则缓蚀性能越好.图6表3参7 |

| Abstract: | 6 quinolinic quatermary ammonium salts(QQA) was prepared after 6 quatermary ammonium salts reacted with quinoline,respectively.The anti-corrosion property of the QQA was characterized through weight loss method,and the factors,such as corrosion inhibitor concentration and temperature,were discussed.The inhibiting mechanism was investigated by means of polarization curves and EIS.The results showed that,the anti-corrosion property(ACP) of 6 QQA was arranged as follows: 1,3-bis-(quinoidine chloride)-2-hydroxy... |
