Abstract The correlation of electronic structure to corrosion inhibition properties of aniline derivatives was studied in terms of semi-empirical quantum chemistry calculation. The results showed the protenated amino species of the p-substituted anlines to be the active part which could combine with metal. A mechanism of inhibition was suggested in which the p-substituted anilines, as inhibitor of iron in acidic medium, formed a film on the iron surface.

Key words: Corrosion inhibitor Aniline derivatives Quantum chemistry calculation CNDO/2
