Thermodynamics and limiting activity coefficients measurements for organic solutes and water in the ionic liquid 1-dodecyl-3-methylimidzolium bis(trifluoromethylsulfonyl) imide was written by Domanska, Urszula;Wlazlo, Michal. And the article was included in Journal of Chemical Thermodynamics in 2016.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:
Bio-fuels like alcs., including butan-1-ol are produced from biomass by fermentation, and distillation Ionic liquids (ILs) are novel attractive solvents, which can be used for removing butan-1-ol from the aqueous fermentation broth. In this work, the 1-dodecyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [DoMIM][NTf2] is proposed as an extractive solvent. The temperature of fusion and the enthalpy of fusion, obtained with DSC, the d. and viscosity of [DoMIM][NTf2] as a function of temperature have been measured over a temperature range (298.15-368.15) K. The limiting activity coefficients 纬鈭?/sup>13, for 65 solutes including alkanes, cycloalkanes, alkenes, alkynes, aromatic hydrocarbons, alcs., water, thiophene, THF, ethers, and ketones in the [DoMIM][NTf2] were determined by gas-liquid chromatog. at six temperatures from 318.15 K to 368.15 K. The partial molar excess Gibbs energies 螖GE,鈭?/sup>1, enthalpies 螖HE,鈭?/sup>1, and entropies 螖SE,鈭?/sup>1 at infinite dilution were calculated from the exptl. 纬鈭?/sup>13 values obtained over the temperature range. The gas-liquid partition coefficients, KL were calculated for all solutes and the Abraham solvation parameter model was discussed. The selectivity and capacity for butan-1-ol/water separation problem were calculated from 纬鈭?/sup>13 and compared to literature values for bis{(trifluomethyl)sulfonyl}imide-based ILs with different cations and with all available data for ILs. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) 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鈥揅6) is higher than in water and generally decreases with a Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
