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. Application of C5H8N2.
Yan, Wenjun;Xu, Huoshu;Ling, Min;Zhou, Shiyu;Qiu, Tong;Deng, Yanjun;Zhao, Zhidong;Zhang, Erpan research published 《 MOF-Derived Porous Hollow Co3O4@ZnO Cages for High-Performance MEMS Trimethylamine Sensors》, the research content is summarized as follows. Trimethylamine (TMA) sensors based on metal oxide semiconductors (MOS) have drawn great attention for real-time seafood quality evaluation. However, poor selectivity and baseline drift limit the practical applications of MOS TMA sensors. Engineering core@shell heterojunction structures with accumulation and depletion layers formed at the interface is regarded as an appealing way for enhanced gas sensing performances. Herein, we design porous hollow Co3O4@ZnO cages via a facile ZIF-67@ZIF-8-derived approach for TMA sensors. These sensors demonstrate great TMA resistive sensing performance (linear response at moderate TMA concentrations (<33 ppm)), and a high sensitivity of ~41 is observed when exposed to 33 ppm TMA, with a response/recovery time of only 3/2 s. This superior performance benefits from the Co3O4@ZnO porous hollow structure with maximum heterojunctions and high surface area. Furthermore, great capacitive TMA sensing with linear sensitivity over the full testing concentration range (0.33-66 ppm) and better baseline stability were investigated. A possible capacitive sensing mechanism of TMA polarization was proposed. For practical usage, a portable sensing prototype based on the Co3O4@ZnO sensor was fabricated, and its satisfactory sensing behavior further confirms the potential for real-time TMA detection.
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., Application of C5H8N2
