Comparative data on corrosion protection of mild steel in HCl using two new thiazoles

This data article includes data described in the investigation report entitled The synergistic role of azomethine group and triazole ring at improving the anti-corrosive performance of 2-amino-4-phenylthiazole (Alamiery et al., 2021). In this data article, a comprehensive effect of 2-Amino4-phenyl-N-benzylidene-5-(1,2,4-triazol-1-yl)thiazole (APNT) and 2-amino-4-phenylthiazole (APT) and optimized process parameter of the inhibitor in 1 M HCl solution was presented using gravimetric techniques and Density functional theory. The presence of the inhibitors influenced the corrosion resistance of mild steel (MS). Inhibition efficiencies values of 98.1% and 94.74% were recorded as results of inhibition of the MS by the inhibiting compounds APNT and ATP respectively. DFT studies observed that the presence of benzylidene to the APNT and the substitution of a triazole in the thiazole ring are adsorption sites that increase the interaction of the APNT molecules with the iron atoms on the MS surface.

Automated summary

This article presents the comprehensive effects of APNT and APT on the corrosion resistance of mild steel, as well as the optimized process parameters of the inhibitor in 1 M HCl solution. The inhibition efficiencies of APNT and ATP were found to be 98.1% and 94.74% respectively. DFT studies revealed the interaction mechanism between APNT molecules and iron atoms on the mild steel surface.
