1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. 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. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Product Details of 21252-69-7

Synthesis of methylal from methanol and formaldehyde catalyzed by Bronsted acid ionic liquids with different alkyl groups was written by Sun, Jiahan;Li, Hansheng;Song, Haoran;Wu, Qin;Zhao, Yun;Jiao, Qingze. And the article was included in RSC Advances in 2015.Product Details of 21252-69-7 This article mentions the following:

The catalytic reaction of methanol with formaldehyde for the preparation of methylal was investigated in various Bronsted acid ionic liquids with different carbon chain length of alkyl groups. The structures, acidities and properties of ionic liquids were exptl. characterized and theor. analyzed. The Bronsted acidity-viscosity-activity correlation for the ionic liquids was studied. Among all these ionic liquids, [C6ImBS][HSO4] exhibited the best catalytic performance, which was ascribed to its strong Bronsted acidity and low viscosity. The catalytic activity of the ionic liquid was near that of concentrated sulfuric acid. The influences of ionic liquid dosage, reaction temperature and molar ratio of methanol to formaldehyde were explored using [C6ImBS]HSO4 as the catalyst. Under the optimal conditions of n(methanol) : n(formaldehyde) : n(ILs) = 2.5 : 1 : 0.0258, 60 °C, and 4 h, the conversion of formaldehyde can reach 63.37%. The ionic liquid [C6ImBS]HSO4 could be reused. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Product Details of 21252-69-7).
