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. 1739-84-0, formula is C5H8N2, Name is 1,2-Dimethyl-1H-imidazole. Their solubility in alcohol is lower than that in water and decreases with increasing molecular weight of the alcohols . Category: imidazoles-derivatives.
Rao, Anil H. N.;Murthy Shekhar, S.;Halashankar Swamy, M. H.;Pranava, H. K.;Kushal, P. research published 《 Understanding the alkaline stability of imidazolium and benzimidazolium functionalized poly(phenylene oxide) based hydroxide exchange membranes》, the research content is summarized as follows. The imidazolium and benzimidazolium groups containing poly(phenylene oxide) (PPO) hydroxide exchange membrane were synthesized and characterized. The membranes were cast by solution casting method yielding transparent, flexible, and rigid membranes. The phys. properties of the membrane, such as ion exchange capacity (IEC), water absorption, and swelling behavior, were investigated. A comparative study of imidazolium and benzimidazolium functionalized PPO membrane focusing on hydroxide conductivity, and alk. stability was comprehensively examined The C2 substituted Me imidazolium membrane displayed unique morphol. and conductivity of 15 mSCm-1 at 25°C. Due to the sterically protected Me group at the C2 position, imidazolium functionalized PPO membrane showed higher alk. stability for 700 h. Furthermore, benzimidazolium cations would be more easily attacked by a nucleophile (OH-) than imidazolium cations, resulting in ring-opening of the heterocyclic ring.
Category: imidazoles-derivatives, 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.
