Abstract: A triphenyl-imidazoline quaternary-ammonium-salt was synthesized from benzoic acid，triethylenetetramine and benzyl chloride. Corrosion inhibition performance was tested by static weight loss method and electrochemical test in HCl solution. Results showed that the corrosion-inhibition rate of the imidazoline quaternary–ammonium-salt with 1.0% concentration was above 99.0%. The synthesized quaternary–ammonium-salt was proved to be a cathode-based mixed-type inhibitor.

摘要： 以苯甲酸、三乙烯四胺、氯化苄为原料合成了3个苯环的咪唑啉季铵盐，用静态失重法和电化学法研究了该缓蚀剂在HCl中的缓蚀性能。实验结果表明，该合成缓蚀剂用量在1.0%（质量分数）时，缓蚀率达到99%以上，且是以阴极型为主的复合型缓蚀剂。
