New glucose derivatives based on 8-hydroxyquinoline have been prepared, and characterized by IR, and NMR (1H and 13C NMR). These compounds were tested as a corrosion inhibitors of mild steel in 1.0 M HCl medium, using mass loss (ML), Potentio-dynamic polarization (PDP), electrochem. impedance spectroscopy (EIS), d. functional theory (DFT) and monte carlo simulation (MCS). The surface of the steel after corrosion test has been characterized by scanning electron spectroscopy (SEM) coupled with energy dispersive spectroscopy (EDS). The corrosive solutions have been characterized by UV-visible spectrometry (UV-vis). The inhibitory efficacy increases with decreasing temperature and increases with inhibitor concentration and reached to 96.5% for the best inhibitor at 298 K and the optimum concentration (1 x 10-3 M). The results of the studies show that these compounds are effective in the corrosion inhibition of mild steel, and the inhibition efficiency depends on the length of the saturated carbon chain. The polarization study shows that the two inhibitors act as mixed type inhibitors. The results of thermodn. studies show that the two compounds are absorbed on the metal surface by chem. bonds (Chemisorption) following Langmuir isotherm. UV-visible anal. shows that the two compounds capable of forming chem. bonds with the iron metal. The theor. studies are in good agreement with those of the exptl. studies. In the experiment, the researchers used many compounds, for example, (3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5Synthetic Route of C12H20O6).
(3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. Tetrahydrofuran (THF) is primarily used as a precursor to polymers including for surface coating, adhesives, and printing inks.Synthetic Route of C12H20O6
