Ionic liquids with high environmental value and adsorption properties are a requirement for the new trend for corrosion inhibitors. Here, we synthesis three new ionic liquids based on dicationic imidazolium (IL1, IL2 and IL3) to produce green inhibitors for stainless steel corrosion in acidic environment. The anionic portion of all prepared ionic liquids is BF-4. New ionic liquids were recognized by means of element inspection, FT-IR, TGA and 1H NMR spectroscopy. All prepared ionic liquids work as good corrosion inhibitors. Where their efficiencies are 91.5%, 98.4% and 83.3% for IL1, IL2 and IL3, resp. at 100 ppm. The counter portion of ILs (BF-4) has a great role in the adsorption process. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Synthetic Route of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Synthetic Route of C11H20N2
