Imidazole is a five-membered heterocyclic moiety that possesses three carbon, two nitrogen, four hydrogen atoms, and two double bonds. 1739-84-0, formula is C5H8N2, Name is 1,2-Dimethyl-1H-imidazole. It is also known as 1, 3-diazole. It contains two nitrogen atoms, in which one nitrogen bear a hydrogen atom, and the other is called pyrrole type nitrogen. Safety of 1,2-Dimethyl-1H-imidazole.
Lee, Yun-Yang;Penley, Drace;Klemm, Aidan;Dean, William;Gurkan, Burcu research published 《 Deep Eutectic Solvent Formed by Imidazolium Cyanopyrrolide and Ethylene Glycol for Reactive CO2 Separations》, the research content is summarized as follows. Solvents made from a reactive ionic liquid, with an imidazolium cation and pyrrolide anion, and ethylene glycol at a wide compositional range were studied for separations of CO2 at low partial pressures (≪0.1 bar up to 1 bar). Thermal anal. and measurements of viscosity and d. show compacting of the liquid upon mixing with enhanced stability achieved by hydrogen bonding. A detailed mechanistic study was performed by IR, quant. NMR, and ab initio calculations that show significant CO2 absorption capacity below 5000 ppm of CO2 in N2. Three reversible routes are found that yield carbonate (major product), carboxylate (moderate), and carbamate (minor) species. With CO2 at 100% RH, bicarbonate along with carbonate species form. The CO2-ethlyene glycol reaction complex, the carbonate anion, is stabilized by the hydrogen bonding and Coulombic interactions, thus preventing evaporation of the solvent during regeneration. This study demonstrates a promising approach to designer green solvents for CO2 separations in open systems such as direct air capture. Functional solvents with very low volatility are demonstrated for reactive CO2 separations suitable for direct air capture.
Safety of 1,2-Dimethyl-1H-imidazole, 1,2-Dimethylimidazole is used in the synthesis of 1,2-dimethyl-3-n-butylimidazoliumchloride and 1,2-dimethyl-3-n-propylimidazolium chloride. It also can be used in the synthesis of 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexafluorophosphate salts.
1,2-Dimethylimidazole is a heterocyclic compound that contains nitrogen and carbon. It can be produced by the reaction between glyoxal and fatty acid in the presence of a base. 1,2-Dimethylimidazole has been shown to have biological properties such as an antioxidant effect. It is also used as a chemical intermediate for production of other chemicals such as 2-methylimidazole and 3-methylimidazole. 1,2-Dimethylimidazole has been shown to react with metal carbonyls to produce methylimines, which are useful intermediates in organic synthesis. The reaction mechanism involves hydrogen bonding and steric interactions between the imidazole ring and the metal carbonyl reactant., 1739-84-0.
