A new benzimidazoles derivatives of 8-hydroxyquinoline have been synthesized and its chemical structure was elucidated and confirmed using different spectral methods such as 1H and 13C NMR spectroscopy.
The inhibitive action of 5-((2-phenylbenzimidazol-1-yl)-methyl)-quinolin-8-ol (Q-H) against the corrosion of mild steel in 1.0 M hydrochloric acid solution were investigated at different temperatures by a series of known techniques such weight loss and electrochemical measurements.
In order to improve inhibition property, the effect of substitution onbenzimidazoles derivatives of 8-hydroxyquinoline towards mild steel corrosion inhibition in hydrochloric acid medium was also studied.
It was found that the studied compounds exhibit a very good performance as inhibitors for mild steel corrosion in 1.0 M hydrochloric acid (HCl).
Results show that the inhibition efficiency increases with decreasing temperature and increasing concentration of inhibitor’s.
