Ionic liquids are used, for example, as corrosion inhibitors for metals, steel, and metal alloys. The method of preventing corrosion through the whole group of these kinds of compounds, called inhibitors, is to use them as additives to aggressive environments, including aqueous electrolytes. In this article, we present the inhibitive effect of imidazolium ionic liquids with 2,5-dihydroxybenzenesulfonate anion on the corrosion of 316L stainless steel in neutral medium. In addition, we demonstrate that when the ionic liquid is used as an additive to the electrolyte solution (1 M Na2SO4) of a sym. carbon/carbon electrochem. capacitor with 316L stainless-steel current collectors, the capacitor lifetime is significantly extended. The ionic-liquid additive inhibits corrosion of the current collector surface and, in effect, prevents activated carbon porous space from being blocked by corrosion products. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Reference of 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 derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Reference of 21252-69-7
