Title: Liquid–liquid equilibria and liquid–liquid interfacial tension measurements of mixtures containing ionic liquids
Abstract: Continuing our research work on ionic liquids new results for liquid–liquid equilibria (LLE) of binary mixtures of the ionic liquids 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C4MIM][NTf2]) or l-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C6MIM][NTf2]) and hexan-1-ol are presented. For the mixture [C4MIM][NTf2] + 1,2-hexanediol the interfacial tension γ between the two liquid phases being in equilibrium has been measured as a function of temperature using a pendant-drop tensiometer. Additionally, for systems [C4MIM][NTf2] + alcohol the influence of impurities like 1-methylimidazole and water on the demixing temperature was investigated.
