Abstract
The effect of 3-[(4-bromo-5-methylthiophen-2-yl) methylene amino]-2-isopropyl quinazolin-4(3-H) one (3-4-5QZ) as a corrosion inhibitor was studied using weight loss measurement. The rate of corrosion was found to be decreased with increasing inhibitor concentration. The adsorption of (3-4-5QZ) on the surface of zinc metal was also investigated according to the Freundlich model. The electronic property of (3-4-5QZ) inhibitor obtained by the semi-empirical quantum chemical calculations, using the PM3 method, revealed a satisfactory correlation with the experimental data.
