Gemini ionic liquids (ILs) are usually known to have significant surfactant behavior. Nanomaterials, on the other hand, are capable of improving interface properties. The current study explores the use of a novel nano gemini imidazolium IL with a mol. structure of a four methylene group spacer for reducing crude oil/water interfacial tension (IFT). The gemini IL was prepared purely by a two-step synthesis method and characterized in different ways. Results revealed that IFT was drastically decreased to 97.8% in the presence of the IL and more decrease was achieved with temperature and pH variations. The high performance of the IL can be attributed to the strong IL amphiphilic nature. The salt effects in the presence of the IL were evaluated with NaCl, MgCl2, and their mixture Results revealed more IFT reduction under salinity conditions because of a remarkable found synergism effect, unlike conventional surfactants. The findings encourage the use of seawater IL solutions in chem. enhanced oil recovery. The obtained salt-free IFT data were precisely reproduced with the well-known Frumkin adsorption isotherm, and the corresponding thermodn. parameters were obtained at different temperatures From thermodn. results, a spontaneous IL adsorption was deduced. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Quality Control of 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Quality Control of 1-Octyl-1H-imidazole
