Abstract

This study aims to prepare 2-hydroselenoacetamide derivatives (5-8) to use some of these compounds as corrosion inhibition for carbon steel in 1 M HCl. The compound C10H10NO2Cl 1 was prepared by reacting between p-aminoacetophenone with chloroacetyl chloride, and then reacted 1 with substituted benzaldehyde to obtain the corresponding derivatives as C17H13N2O4Cl 2, C18H16NO4Cl 3 and C19H18NO4Cl 4. The last step in this study was conducted to obtain the organic hydroselenoacetamide such as C10H11NO2Se 5, C17H14N2O4Se 6, C18H17NO4Se 7, and C19H19NO4Se 8 by reacting chloroaminochalcone and sodium hydrogen selenide. All compounds were characterized by Fourier Transform Infrared Spectroscopy (FTIR), proton nuclear magnetic resonance (1H-NMR), and elemental analysis (CHN). The corrosion inhibition activity of C17H14N2O4Se 6, C18H17NO4Se 7 and C19H18NO4Cl 4 for carbon steel in 1 M HCl solution was investigated by using weight loss methods and electrochemical study. The activation energy of the corrosion reaction was also calculated. The effect of different concentrations and temperatures on inhibition efficiency was investigated. The results showed that the corrosion rate decreased with the increase of the concentration of inhibitors, while the inhibition efficiency and covered area decreased with an increase in the temperature. Polarization studies demonstrated that the inhibitors were of mixed type. The purpose of this study was to prepare, characterize and evaluate the corrosion inhibition activity of hydroselenide compounds for carbon steel in 1 M HCl.

Abstract

This study aims to prepare charge transfer complexes derived from organochalcogenide of arylamide derivatives with different quinones. A new charge-transfer complexes have been developed through a direct reaction between (PhNHCOCH2)2Se, (o-CH3PhNHCOCH2)2Se, and (PhCH2NHCOCH2)2E, where E = S, Se, and Te are electron donors and different quinones are electron acceptors. The quinones used in the reaction were 2,3-dichloro-5,6-dicyanobenzoquinones (DDQ), 7,7’,8,8’-tetracyanoquinodimethane, and tetracyanoethane. The electron donors and electron acceptor mol were 1:1, and the reaction was conducted in acetonitrile. Infrared, 1H and 13C-NMR spectroscopic data characterized all complexes. The complexes’ antioxidant activity was evaluated through α,α-diphenyl-β-picrylhydrazyl at 10–0.312 mg/mL. The results showed that all complexes exhibited promising antioxidant activities. Among them, (PhCH2NHCOCH2)2S·DDQ compound had the least IC50 value of 6.725 mg/mL, indicating a potent scavenging property compared to other compounds. The molecular structures of charge-transfer complexes were investigated using hybrid density functional theory (B3LYP) and basis set 3-21G. We obtained geometrical structures' highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) surfaces and energy gaps through geometric optimization. We also investigated the molecular shapes and contours of the prepared compounds through geometrical optimization and compared the HOMO energy of the CT compounds to investigate donor and acceptor properties.
