摘要：

The efficiency of various imidazole derivatives as zinc corrosion inhibitors in hydrochloric acid (HCl) was investigated using electrochemical and gravimetric methods. A difference in efficiency (z) was observed with the introduction of different substituents into a imidazole skeleton. It was established that substituents which increased the electron density at the reaction center improved the corrosion inhibiting properties of the heterocyclic compound. A linear correlation between reaction kinetic data and the sum of the polar substituent constants was obtained.
