Abstract:

In this work, we report a study on the synthesis and characterization of a new series of Schiff bases based on imidazo[ 1,2-a]pyridine (IMP) scaffold, and the evaluation of their ability to inhibit the corrosion of mild steel in 1M HCl. Several techniques were employed such as mass loss techniques, Potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS). The obtained results showed that these inhibitors, namely (E)-N-(2-phenylimidazo[1,2-a]pyridin-3- yl)-1-(1H-pyrrol-2-yl)methanimine(IMP1),(E)-N-(2-phenylimidazo[ 1,2-a]pyridin-3-yl)-1-(thiophen-2-yl)methanimine (IMP2) and (E)-1-(5-nitrothiophen-2-yl)-N-(2-phenylimidazo[ 1,2-a]pyridin-3-yl)methanimine (IMP3), acted only by reducing the cathode area without changing the mechanism of the cathodic reaction. Also, the effectiveness of the inhibition increases with increasing concentration of the inhibitors. The adsorption of the studied compounds on the surface of mild steel follows the Langmuir isotherm model. Finally, we highlighted the existence of a correlation between the molecular structure of the tested inhibitors and their anticorrosion activity. Recent Publications 1.
