SYNTHESIS AND CHARACTERIZATION OF CORROSION INHIBITORS BASED ON CARBAMIDE AND BETA CYCLODEXTRIN
Abstract
This paper presents the synthesis of corrosion inhibitors based on carbamide (NH2)2CO and beta cyclodextrin (β-CD), as well as the investigation of their properties. The synthesis process involves dissolving carbamide and β-CD in distilled water, adding phosphoric acid, and mixing at 70°C. The solution is then cooled, and the precipitate is separated and dried. The inhibitor is purified in three stages. Scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) were used to analyze the corrosion process on steel surfaces and the effectiveness of the inhibitor. SEM results indicate that the inhibitor forms a protective layer on the steel surface, significantly improving the metal's resistance to corrosion. The findings suggest that the synthesized inhibitor could serve as an effective tool for corrosion control in industrial applications.
