Hoseinzadeh, A. R.; Javadpour, S. published the artcile< Electrochemical, thermodynamic and theoretical study on anticorrosion performance of a novel organic corrosion inhibitor in 3.5% NaCl solution for carbon steel>, SDS of cas: 96-53-7, the main research area is carbon steel sodium chloride corrosion inhibitor electrochem anticorrosion property.
The theor. and electrochem. performance of a novel organic corrosion inhibitor 3,4-dihydro-3-[2-mercaptothiazolidine]indol-2-one (DMI), for API 5L Grade B carbon steel in 3.5% NaCl, was evaluated by potentiodynamic polarization (Tafel), electrochem. impedance spectroscopy (EIS) and d. functional theory (DFT) for quantum chem. studies. Potentiodynamic studies confirmed that DMI was a mixed organic corrosion inhibitor type which specially affects the cathodic branch. The inhibition efficiencies of reactants, DMI and acetylcysteine followed the following order at 25oC and 200 ppm: DMI (87%) > isatin (71%) > 2-thiazoline-2-thiol (62%) > acetylcysteine (54%). EIS measurements illustrated the charge transfer controlled corrosion process. The Langmuir adsorption isotherm model of DMI was adopted. Surface studies were performed using SEM. Activation and adsorption thermodn. parameters of DMI were computed. The magnitude of ΔGoads and the sign of ΔHoads concluded that the adsorption occurred through chemisorption. Quantum chem. calculations of four corrosion inhibitors were used for investigating the mol. structure effect on inhibition efficiency.
