This study proposes to use mol. aggregation method of organic ionic liquid mols. (OILMs) to intensify adsorption and corrosion inhibition to copper surface in sulfuric acid solution Three new single imidazole-type OILMs including long carbon chain were synthesized, which were characterized by different methods such as NMR (NMR) and elemental anal. The results suggest that the OILMs could process regular mol. assembly in sulfuric acid solution The formed OILMs aggregates have been shown dependence on the OILMs concentrations and aggregation time. The chem. adsorption of the OILMs aggregates on copper surface was demonstrated by various means including attenuated total reflection IR spectroscopy (ATR-IR), XPS, X-ray diffraction (XRD), and spectroscopic ellipsometry and contacting angles, and at. force microscopy (AFM) as well as SEM (SEM) imaging. Thus, the hydrophobic adsorption layers of the OILMs aggregates were yielded on copper surface. The electrochem. survey suggests that the OILMs aggregates present nice corrosion resistance effect to copper in sulfuric acid solution (the maximal corrosion inhibition efficiency, >93%). The results were further understood by the theor. simulation computation. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Recommanded Product: 21252-69-7).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Recommanded Product: 21252-69-7
