📖 New synthetic corrosion inhibitors. The 8-hydroxyquinoline and its derivatives.

In this work, we have synthesized and characterized novel organic compounds. These organic compounds were characterized by UV-visible spectroscopy (UV-Vis), Elemental analysis (EA), Infrared (IR), Mass spectrometry (MS), 1H-NMR and 13C-NMR . These organic compounds were tested as corrosion inhibitors of mild steel in 1.0 M HCl by experimental and theoretical investigations. The surface of the steel before and after corrosion was characterized by the Scanning Electron Microscope coupled with Dispersive Energy Analysis (SEM-EDAX) and the gravimetric solution was analyzed by UV-visible spectrometry.
