《Synthesis, structural and anticorrosion properties of diethyl(methoxyphenyl(phenylamino)methyl)phosphonate derivatives: Experimental and theoretical study》 was published in Journal of Molecular Structure in 2020. These research results belong to Moumeni, Ouahiba; Chafaa, Salah; Kerkour, Rachida; Benbouguerra, Khalissa; Chafai, Nadjib. COA of Formula: C8H8O2 The article mentions the following:
The authors synthesized three di-Et (phenylamino) Me phosphonate derivatives: Diethyl(phenyl(phenylamino)methyl)phosphonate (DEPAMP), Diethyl(2-methoxyphenyl(phenylamino)methyl)phosphonate (o-DEPAMP), Diethyl(4-methoxyphenyl(phenylamino)methyl)phosphonate (p-DEPAMP), whose the yields were 92%, 86% and 88%, resp. After confirmation of their structures by UV-visible, FTIR and NMR spectroscopic methods, the synthesized compounds were studied as corrosion inhibitors of XC48 C steel in 1 mol L-1 HCl medium. P-DEPAMP is a better inhibitor in 10-3 mol L-1. Atomic Force Microscopy (AFM) was required for metallic surface characterization and the quantum chem. parameters were calculated using the D. Functional Theory (DFT) method. The adsorption energies of the inhibitors on Fe (110) surface in gas and aqueous phases were premeditated adopting the Mol. Dynamics Simulation (MDS) method. This study described the successful performance of these compounds in corrosion using weight loss measurements, Potentiodynamic Polarization and Electrochem. Impedance Spectroscopy (EIS), and discusses the correlation between exptl. and theor., presumed DFT and MDS finding. The adsorption studies on surface were in agreement with the Langmuir adsorption isotherm model. The effects of position of OCH3 group located at ortho and para or without in chem. structure of aminophosphonates on the corrosion inhibition efficiencies of the compounds were also studied. The experimental process involved the reaction of 2-Methoxybenzaldehyde(cas: 135-02-4COA of Formula: C8H8O2)
2-Methoxybenzaldehyde(cas: 135-02-4) is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.COA of Formula: C8H8O2
