Flavonoids, alkaloids, glucosides and tannins with good corrosion inhibition are the main natural components in plants. In this work, procyanidin B2 (PCB2), a natural flavonoid, was firstly isolated from Uncaria laevigata. Corrosion inhibition, chem. reactivity and adsorption of PCB2 on Q235 carbon steel were described by exptl. and theor. studies. The inhibition performance of PCB2 as a green corrosion inhibitor was evaluated by electrochem. and gravimetric tests. The binding active sites and activities thereof on the steel surface were illustrated by quantum chem., and the equilibrium configuration was predicted by mol. dynamics simulation. PCB2 exhibits good corrosion inhibition on Q235 steel over a wide temperature range. The electrochem. results show that PCB2 is a mixed inhibitor, and its inhibition efficiency increases with the addition of PCB2 concentration Moreover, the protective film is formed on the steel and the active corrosion sites are blocked significantly by surface anal. Addnl., the theor. calculation proves a strong interaction between PCB2 mol. and carbon steel. Besides, the antimicrobial activity was also preliminarily studied. This suggests that PCB2 exhibits better antimicrobial activity against many Gram-pos. and Gram-neg. bacteria. As a novel green corrosion inhibitor and antimicrobial agent, PCB2 is worthy of further exploitation. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8SDS of cas: 29106-49-8).
(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.SDS of cas: 29106-49-8
