摘　　要：以油酸和羟乙基乙二胺为原料,二甲苯为携水剂合成咪唑啉缓蚀剂,通过正交试验得出其最佳合成条件为:油酸与羟乙基乙二胺的摩尔配比为1∶1.2,酰化温度为160℃,酰化时间为4h,环化温度为220℃。将合成的咪唑啉缓蚀剂分别与十二烷基苯磺酸钠、KI和Na2WO4复配,得出咪唑啉缓蚀剂和十二烷基苯磺酸钠最佳复配比为1∶1,与KI为1∶1,与Na2WO4为1∶2。An imidazoline corrosion inhibitor was synthesized with oleic acid, hydroxyethylethylene diamine as raw materials,the dimethylbenzene was used as water carrying agent.The optimum synthesis conditions were ob- tained through orthogonal test：Molar ratio of oleie acid andhydroxyethylethylene diamine was 1：1.2; the temperature of aeylation reaction was 160℃; the time of aeylation reaction was 4h; the temperature of cyclization reaction was 220℃. The complex with sodium dodecyl benzene sulfonate,potassium iodide and sodium tungstate were researched and the best ratios are as follows： The ratio of sodium dodeeyl benzene sulfonate and the corrosion inhibitor is 1 ： 1. The ratio of potassium iodide and the corrosion inhibitor is 1：1.The ratio of iodide sodium tungstate and the corro- sion inhibitor is 2：1.
