ABSTRACT:
One of the most efficient, affordable, and realistic corrosion inhibition methods is organic molecules containing oxygen (O), nitrogen (N), sulphur (S), as well as phosphorus (P) heteroatoms in their molecular structures. The efficiency of heteroatoms in inhibiting metallic corrosion is as follows: P > S > N > O. The metal-inhibitor interactions entail charge sharing between heteroatoms and the unoccupied d-orbitals of the metal; hence, a heteroatom with a lesser value of electronegativity is far more powerful to bind firmly with metallic surface. Corrosion inhibitor compounds comprising sulphur and phosphorus are discussed in this article. Organic compounds containing heteroatoms (such as sulphur, phosphorus, nitrogen and oxygen) have a remarkable ability to suppress corrosion. The existence of lone pair electrons and electrons in the molecule, which allows them to readily deposit on the metal surface, is credited with their efficiency. Organic compounds with fewer electronegative heteroatoms, on the other hand, have a greater inhibitory efficiency (IE) owing to the ease with which lone pair electrons migrate. The goal of this study is to identify potential corrosion inhibitors based on Sulfur and Phosphorus heteroatoms.
