1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Reference of 21252-69-7

A novel class of Gemini imidazolium surfactants 1,3-bis(3-alkylimidazolium-1-yl) propane bromide [Cn-3-Cni.m.]Br2 (n = 8, 10, 12) were synthesized and characterized by FT-IR, 1H NMR and elemental anal. The surface activity and aggregation behavior of [Cn-3-Cni.m.]Br2 (n = 8, 10, 12) were investigated by surface tension, conductivity and steady fluorescence methods. A series of surface active parameters, including cmc, Γmax, pC20, cmc/C20, Amin, γcmc and Πcmc were obtained from surface tension measurement. It was indicated that Gemini imidazolium surfactants with the longer alkyl chain showed the higher surface activity. The thermodn. parameters of micellization process, namely, standard Gibbs free energy (ΔGοm), enthalpy (ΔHοm) and entropy (ΔSοm) were derived from conductivity measurement at different temperatures The micropolarity and the mean aggregation number (Nagg) of micelles were evaluated from steady fluorescence spectra. The results revealed that the micropolarity and Nagg of micelles decreased with the increase of hydrocarbon chain length. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Reference of 21252-69-7).
