Computational Chemistry Study on the Corrosion Inhibitor Performance Of 1,3,4-Oxidizole Derivatives Against The Corrosion Of Mild Steel In Chloric Acid

The objective of this research is to use computational chemistry through the study of three heterocyclic compounds of 1,3,4-oxidizole derivatives. Quantum chemical calculations based on density function theory (DFT) method were performed on three nitrogen-bearing heterocyclic compounds used as corrosion inhibitors for the mild steel in acid media to determine the relationship between the molecular structure of inhibitors and inhibition efficiency. The structural parameters, such as energy and distribution of highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO), the charge distribution of the studied inhibitors, the absolute electronegativity (χ) values, and the fraction of electrons (∆N) transfer from inhibitors to mild steel were also calculated and correlated with inhibition efficiencies. The results showed that the inhibition efficiency of inhibitors increased with the increase in energy of HOMO and decrease in energy gap of frontier molecular orbital, and the areas containing N and O atoms are most possible sites for bonding the steel surface by donating electrons to the mild steel.
