An Exploratory Experimental Analysis Backed by Quantum Mechanical Modeling, Spectroscopic, and Surface Study for C-Steel Surface in the Presence of Hydrazone-Based Schiff Bases to Fix Corrosion Defects in Acidic Media.

This work focuses on developing corrosion control and protecting the environment by creating affordable, sustainable, environmentally friendly, and efficient corrosion resistance chemicals. That is, through synthesized three hydrazone Schiff bases -2-(1-hydrazonoethyl)thiazole (), 2-(()-((()-1-(thiazol-2-yl)ethylidene)hydrazono)methyl)phenol (), and 2-(()-((()-1-(pyridin-2-yl)ethylidene)hydrazono)methyl)phenol () and corrosion inhibitors for C-steel in 8 M HPO solution that were studied. The chemicals were analyzed by using H NMR and C NMR spectroscopy to learn more about them.
