| 摘 要： | 开发咪唑啉型缓蚀剂及其衍生物,探讨其腐蚀机理对于金属的腐蚀防护意义重大.为此,用月桂酸和二乙烯三胺合成了咪唑啉型缓蚀剂,通过静态失重法、线性扫描极化曲线法考察了其在5%HCl溶液中的缓蚀电化学性能及与KI的协同作用.结果表明:该缓蚀剂对A3碳钢的腐蚀具有明显的抑制作用,浓度为30 mg/L时缓蚀率达到99.0%;可以有效抑制腐蚀过程中的阳极反应;与Ⅺ有良好的缓蚀协同作用,10mg/L缓蚀剂与10 mg/L KI复配可以使缓蚀率达到99.2%,并且能将腐蚀速率控制在0.6 g/(m2·h)以下. |

| Abstract: | Corrosion inhibitor imidazoline was prepared by using dodecanoic acid and diethylenetriamine as the raw materials.The corrosion inhibition performance of imidazoline for carbon steel A3 in 5 % HC1 solution was evaluated by measurement of static weight-loss and linear scanning polarization curve, and its synergistic inhibition action with KI was investigated.Results indicate that the imidazoline as an inhibitor is effective to retard the corrosion of the carbon steel, and a corrosion inhibition rate of 99% i... |
