College of Materials and Chemical Engineering,Sichuan University of Science corrosion inhibitors; weight loss measurement; polarization curve Abstract. A new chloroacetic-acid modified imidazoline (CAMI) was synthesized via the

3、quaternization of imidazoline intermediate, obtained from the amidation and cyclization reactions of benzoic acid and diethylene triamine, with chloroacetic-acid. The performance of the synthesized compound CAMI as corrosion inhibitor for Q235 carbon steel in 5% sulfuric acid solution was investigat

4、ed by weight loss measurement and potentiodynamic polarization technique. The results show that CAMI possesses strong inhibitive effect on the corrosion of Q235 carbon steel in acid medium and restrains the corrosion without changing the cathodic and anodic corrosion mechanism as a mixed-type inhibi

5、tor. Introduction Every year, heavy losses are caused by corrosion of metals in natural environment, industrial production, oil and gas exploration and production. The application of corrosion inhibitors is one of the most effective and practical methods for protection metal against corrosion in var

6、ious kinds of corrosion medium, especially in acidic media for that acid solutions are widely used in industry, such as acid pickling, industrial acid cleaning, acid descaling and oil-well cleaning. The majority of well-known inhibitors are organic compounds containing nitrogen, sulfur and/or oxygen atoms 1-3. Among the various organic inhibitors used for inhibiting the corrosion of metal in acid medium, nitrogen-based organ
