The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . 1739-84-0, formula is C5H8N2, Name is 1,2-Dimethyl-1H-imidazole. In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with an increase of the alkyl chain length of the alcohols. SDS of cas: 1739-84-0.
Wang, Jian;Wu, Junshuang;Wu, Wenqing;Tong, Jing research published 《 Estimation of the polarity and prediction of the molar surface Gibbs energy for amino acid ionic liquids – [C4Dmim][Gly] and [C4Dmim][Ala]》, the research content is summarized as follows. 1-Butyl-2,3-dimethylimidazolium glycine ([C4Dmim][Gly]) and 1-butyl-2,3-dimethylimidazolium alanine ([C4Dmim][Ala]) were synthesized by neutralization method and characterized by 1H NMR and 13C NMR spectrum. The exptl. values of the d., surface tension and refractive index of two amino acid ionic liquids were measured by standard addition method. Firstly, the polarity coefficients of [C4Dmim][Gly] and [C4Dmim][Ala] were calculated by polarity coefficient (P), and the polarity trend of other ionic liquids (ILs) was predicted. For the same anion, the polarity values of the same series of ILs decrease with increasing carbon chain length, and the anion species also affect the polarity of ILs. Secondly, according to the relationship between the slope of the new Eotvos empirical equation and the molar surface entropy (s), the polarity values of other ILs were also estimated and the conclusion obtained was basically consistent with polarity coefficient Furthermore, the predicted molar surface Gibbs energy values of samples were obtained by the new Eotvos empirical equation, and the predicted values were highly consistent with the corresponding exptl. values.
1739-84-0, 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., SDS of cas: 1739-84-0
