Chemically functionalized of 8-hydroxyquinoline derivatives as efficient corrosion inhibition for steel in 1.0 M HCl solution: Experimental and theoretical studies
The challenge of this work is the functionalization of new 8-hydroxyquinoline derivatives by a simple method achieving a very good yield (80-90%).The corrosion inhibition performance of two neworganic compounds derived from quinolin-8-ol, namely, BMQ and DEMQ for mild steel in 1.0 M HCl solution was studied usingPotentiodynamic polarization (PDP)and electrochemical impedance spectroscopy (EIS).Scanning electron microscopy (SEM) coupled with the energy dispersive spectroscopy (EDX) were used to characterize and analyze the surface of steel.The theoretical study wasalso carried out by DFT calculations (structure-reactivity) and Monte Carlo, MC (inhibitor-surface) simulations. The electrochemical results showed that both studied molecules provide high resistance and that the inhibition efficiency (eta%) reaches 94% at 10(-3) M for BMQ. PDP measurements revealed that these compounds function as mixed type corrosion inhibitors. In addition, they can be adsorbed on the steel surface by chemical bonds following Langmuir adsorption isotherm. Also, both inhibitors remain effective at high temperatures (86% at 328 K for the concentration 10(-3) M).DFT calculations show that the free heteroatom doublets of oxygen (O), nitrogen (N) and the methyl groups (-CH3) favor the sharing of electrons between the studiedmolecules and the surface of the steel. The data of theoretical methods (DFT and MC) supported the experimental findings.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 302964-08-5, you can contact me at any time and look forward to more communication.
