摘　　要：选用二甲苯、活性氧化铝和硼酸等作为脱水剂或催化剂,分别合成了三种油酸基咪唑啉,利用红外光谱对咪唑啉的结构进行了表征,使用质量损失法、极化曲线法和交流阻抗法等技术比较了三种油酸基咪唑啉缓蚀剂在H_(2)S/CO_(2)饱和的高矿化度溶液中对碳钢的缓蚀性能。结果表明,使用活性氧化铝催化合成的咪唑啉缓蚀效果最好。Three types of oleic imidazoline inhibitors were synthesized by using xylene,activated alumina and boric acid as dehydrating agent or catalyst.The structure of imidazoline was characterized by infrared spectroscopy.The inhibition performance of the three oleic imidazoline inhibitors on carbon steel in highly mineralized solution saturated with H_(2)S/CO_(2)was compared by applying techniques such as weight loss,polarization curve and AC impedance.The findings showed that the inhibitor synthesized with activated alumina as catalyst has the best inhibition effect.
