Abstract

The prime objective of the present research is to explore the green synthesis of pyridine derivative by functionalizing amino acid vanillin (Py-Va) using the ultrasound method and its application as a novel corrosion inhibitor for P110 steel in oil formation water (OFW). The results report that Py-Va inhibits P110 steel corrosion and represents a significant decrease in corrosion rate with the rising dose at certain temperatures. Electrochemical experiments manifest that Py-Va can restrain reactions of the cathode and anode of P110 steel. The molecular adsorption of Py-Va is governed by Langmuir isotherm with the chemical mechanism participation. The morphology maps of surface analysis support the creation of an inhibitive layer of Py-Va over the steel surface. Biological activity reveals a significant reduction in the sulfate-reducing bacteria (SRB) after Py-Va addition. Molecular docking and Root Mean Square deviation (RMSD) as used to analyze the Py-Va and SRB protein interaction.
