Abstract The electronic structures of aniline and its halogenated and methylated derivatives, N-phenylyl dodecyl amine and its methylated derivatives with substituents at different positions have been calculated by semiempirical method of Quantum Chemistry. The relation between the inhibitive efficiency of the above compounds in acid media for mild steel and their electronic structures has been discussed. A tentative interpretation is given for the phenomenon that when the inhibitors are substituted with the same kind of substituents at different positions in the molecule, or with different substituents at the same position, they exhibit different inhibitive efficiency. The mechanism of corrosion inhibition has been explained from the point of view of electron transfer. The information provided in this paper could be probably useful for developing new inhibitors of better quality.
