【Abstract】 Quaternary ammonium bis-imidazoline was synthesized. The anti-corrosion property in HCl-H₂S-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-H₂S-NaCl-H₂O was investigated by means of polarization curves and SEM. Results showed that this compound attained good inhibition on corrosion of carbon steel in HCl-H₂S-NaCl and 10% HCl solutions, and mainly retarded the anodic process of corrosion and belonged to a mixed-type inhibitor.更多还原
