Abstract: The new group of surfactants was synthesized based on corn oil and monoethanolamine and their inhibiting action on the corrosion of mild steel in CO2-saturated solution was investigated by means of potentiodynamic polarization and linear polarization resistance corrosion rate. The results revealed that, the studied surfactants were an excellent inhibitors and the inhibition efficiencies obtained from potentiodynamic polarization and Linear polarization resistance corrosion rate were in good agreement. Potentiodynamic polarization studies clearly revealed that surfactants acted essentially as the mixed-type inhibitors. Thermodynamic and kinetic parameters were obtained from potentiodynamic polarization, which suggested that at 323 K, the adsorption of inhibitors on the metal surface obeyed Langmuir adsorption isotherm model

Abstract: Acyclic Schiff base ligand containing N2O3 donor atoms was synthesized by the reaction of 2,6 – diformyl – 4 – ter-butylphenol and 4 – aminoantipyrine in 1:2 molar ratio. The synthesized ligand (H1L) and Ln(III) complexes [Ln= LaIII, CeIII and GdIII] were characterized by1HN.M.R., 13CN.M.R., mass spectrometry, UV /Visible, FTIR, Elemental analysis (C.H.N.), Magnetic susceptibility and Molar conductivity measurements. A seven coordinated complex obtained through N2O3 and two chloride atoms coordinated to metal ions.
