| 摘 要： | 利用两步法合成了双咪唑啉季铵盐化合物，通过失重法研究了该化合物在1g／L HCl 0．16g／L H2S 1g／L NaCl溶液和10％的盐酸溶液中对碳钢的缓蚀性能，讨论了用量、温度、时间对缓蚀性能的影响，并通过极化曲线和扫描电镜研究了该化合物的缓蚀机理。结果表明，该化合物在HCl-H2S-NaCl-H2O和10％的盐酸腐蚀环境中对碳钢具有良好的缓蚀作用，是一种以阳极控制为主的混合型缓蚀剂。

| Abstract: | Quaternary ammonium bis-imidazoline was synthesized. The anti-corrosion property in HCl-H_2S-NaCl and 10% HCl solutions was characterized with weight loss method. Factors such as concentration, temperature and time were discussed. The inhibiting mechanism in HCl-H_2S-NaCl-H_2O was investigated by means of polarization curves and SEM. Results showed that this compound attained good inhibition on corrosion of carbon steel in HCl-H_2S-NaCl and 10% HCl solutions, and mainly retarded the anodic process of corrosion and belonged to a mixed-type inhibitor. |
