It is of great significance to develop high-efficiency and green corrosion inhibitors for Q235 steel under acidic conditions. In this study, resveratrol was chem. modified to resveratrol-3-O-β-D-glucopyranoside (R3GP) in order to increase its solubility and complexation ability with metal ions. The obtained electrochem. anal. results indicated that R3GP was an anode-based mixed inhibitor, whose inhibitive efficiency was obviously higher than that of resveratrol (400 mg/L, 90.33% vs. 69.52%). The adsorption of R3GP over steel surface followed Langmuir isotherm, and the inhibition efficiency was still maintained 82.60% at 328 K. Surface analyses (SEM and AFM) proved the existence of R3GP on Q235 steel surface to form a corrosion-protective film. Quantum chem. calculations revealed the R3GP mol. could be more stable on Q235 steel surface. Mol. dynamic simulations also manifested that R3GP was absorbed more strongly on the metal surface in a parallel mode and had a large bind energy (561.66 kJ/mol). This study involved multiple reactions and reactants, such as (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6Synthetic Route of C20H22O8).
(2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Synthetic Route of C20H22O8
