The corrosion inhibition performance of two pyrimidine derivatives namely 5-styryl-2,7-dithioxo-2,3,5,6,7,8-hexahydropyrimido[4,5-d] pyrimidin-4(1H) one (PP-1) and 5-(2-hydroxyphenyl)-2,7-dithioxo-2,3,5,6,7,8-hexahydropyrimido[4,5-d]-pyrimidin-4(1H) one (PP-2) on N80 steel corrosion in15% HCl has been studied using gravimetric method, electrochemical impedance spectroscopy (EIS),potentiodynamic polarization, atomic force microscopy (AFM), scanning electron microscopy (SEM), DFT,molecular electrostatic potential and Monte Carlo simulation. The corrosion inhibition efficiencies atoptimum concentration (250 mg/L) are 89.1% (PP-1) and 73.1% (PP-2) respectively at 308 K. The corrosioninhibition efficiency increases with increase in concentration and decreases with temperature. PPsobeyed Langmuir adsorption isotherm. AFM and SEM analyses supported formation of protectivefilm onN80 steel in presence of inhibitors. DFT and Monte Carlo simulation calculations supported experimentalresults.
