A kind of Fatty Amido Alkylimidazoline Compound is synthesized by the reaction of a selected fatty acid and diethylenetriamine. Its inhibiting behavior on mild steel corrosion in H 2S and NaCl-containing hydrochloric acid solutions is investigated by means of weight loss and electrochemical methods. The results show that this imidazoline derivant is a good corrosion inhibitor to mild steel in H 2S and NaCl-containing hydrochloric acid medium. The inhibition efficiency increases with the increase in concentration for the imidazoline compound studied but is temperature-independent. The synthesized compound is a mixed-type corrosion inhibitor but is mainly controlled by anodic process. The corrosion inhibition properties are superior to the similar kinds of foreign products.
