Abstract

A new imidazoline compound, 2-(2-tribromomethyl-4,5-dihydro-imidazol-1-yl)-ethylamine (3-IM) was synthesized and its inhibitory effect on the corrosion of mild steel in 0.5 M HCl solution was examined by weight loss, potentiodynamic polarization measurements and electrochemical impedance spectroscopy (EIS). The experimental results show that 3-IM behaves as a mixed-type inhibitor and the inhibition efficiency increases with the increasing compound concentrations. The adsorption actions of 3-IM molecules are well fitted by Langmuir isotherm, while the protection property of the adsorptive layer decreases as the temperature increases.
