Four imidazoline inhibitors have been synthesized and determined by IR and UV spectral analyses. The inhibition efficiency was measured using weight loss and electrochemical methods. It is found that percentage inhibition corrosion is increased as in following order: compound I<Ⅱ<Ⅲ<Ⅵ. The relationship between structure of the compounds and corrosion inhibition efficiency is explored from experiment. Through measured results and theoretical analyses, it is indicated that imidazoline with P-π conjugated system and electron donor group, particularly, the substituent aromatic group, introduced to imidazoline ring can improve the inhibition efficiency of imidazoline derivatives.
