The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . 10111-08-7, formula is C4H4N2O, Name is 1H-Imidazole-2-carbaldehyde. 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 C4H4N2O.
Pan, Yong;Yu, Xi research published 《 Preparation of Zeolitic Imidazolate Framework-91 and its modeling for pervaporation separation of water/ethanol mixtures》, the research content is summarized as follows. Zeolitic Imidazolate Framework (ZIFs) have received much attention in recent years because of their good compatibility with polymer, and their ultramicroporosities that are in the range of the kinetic diameter of several important gas and liquid mols. In this study, three different ZIF particles, i.e., ZIF-90 and its derivatives (ZIF-91 and ZIF-92) were synthesized and incorporated into polydimethylsiloxane (PDMS) matrix to fabricate ZIF/PDMS nanocomposite membrane for pervaporation recovery of ethanol. The morphologies and structures of ZIF particles and their nanocomposite membrane were characterized by various techniques. The results show that ZIF-91 particles with hydroxyl functional groups have good compatibility with PDMS and are dispersed well in PDMS matrix. Meanwhile, ZIF-91/PDMS nanocomposite membrane have higher pervaporation performance compared to ZIF-90/PDMS and ZIF-92/PDMS nanocomposite membrane with the same loading of 20 weight%. The effects of particle loading, feed concentration and temperature on the separation performance of ZIF-91/PDMS membranes were also investigated. The results indicate that ZIF-91/PDMS-20 weight% membrane showed a prominent separation factor of 15.8 at 55°C with a comparable total flux of 846 g/(m2 h), which were higher than that of pure PDMS (4.1, 496 g/(m2 h)). In addition, the pervaporation modeling for the flux and separation factor of ZIF-91/PDMS membrane were established with quadratic equations of temperature and feed concentration, which can be used to predict separation performance according to the experiment conditions.
Application of C4H4N2O, 1H-Imidazole-2-carbaldehyde, also known as 1H-Imidazole-2-carbaldehyde, is a useful research compound. Its molecular formula is C4H4N2O and its molecular weight is 96.09 g/mol. The purity is usually 95%.
1H-Imidazole-2-carboxaldehyde is a novel PTP1b inhibitor with potential application to treat type 2 diabetes.
1H-Imidazole-2-carboxaldehyde is a broad-spectrum antimicrobial that has been shown to inhibit the growth of bacteria by interfering with protein synthesis. It binds to the cytosolic protein and receptor molecule, which are involved in the activation of bacterial enzymes. Imidazole-2-carboxaldehyde reacts with anhydrous sodium and copper complex to produce hydrogen bonds, which prevent the formation of the nitrogen atoms necessary for cellular processes. This chemical also has biological properties such as glyoxal, which inhibits bacterial growth by reacting with amino groups on proteins., 10111-08-7.
