通过优化分子结构设计,以甲醇反应法合成羟基月桂酸咪唑啉,采用氯乙酸钠法将羟基月桂酸咪唑啉缓（简称缓蚀剂LAH）与氯乙酸反应生成季铵盐以提高化合物的稳定性和水溶性。通过失重法实验研究缓蚀剂LAH在5%氯化钠饱和CO2水溶液中的缓蚀性能与缓蚀剂浓度、介质温度和腐蚀时间的关系。实验结果表明,缓蚀剂LAH具有良好的缓蚀性能,LAH是以抑制腐蚀阳极过程为主的混合型缓蚀剂。

The imidazoline corrosion inhibitors synthesized in this paper is hydroxy lauric imidazoline by the method of methanol reaction. Hydroxy lauric imidazoline is converted into Hydroxy lauric imidazoline quaternary ammonium salt with sodium chloroacetate to improve its compounds stability and water-soluble. The result of weight-loss experiment proved that inhibitor LAH has good performance in 5% NaCl CO2 saturated. The polarization curves prove that the inhibitor LAH is a mixed corrosion inhibitors, which primarily leads to the inhibition of the anodic process.
