Imidazole and Its Derivatives as Inhibitors for Prevention of Corrosion of Copper
Abstract
The aim of this work was to investigate the efficiency of imidazole and its derivatives 4-methylimidazole, 4-methyl-5-hydroxymethylimidazole, 1-phenyl-4-methylimidazole, 1-(p-tolyl)-4-methylimidazole for corrosion inhibition of copper in 0.5M hydrochloric acid. Corrosion inhibition was studied using impedance spectroscopy and potentiodynamic methods. Results obtained from the AC impedance measurements are in good agreement with those obtained from d.c. polarization measurements. The copper samples were also analyzed by scanning electron microscopy (SEM) and X-rays microanalysis. These studies have shown that 1-(p-tolyl)-4-methylimidazole has the highest inhibitory efficiency.
