Abstract	The solubility of 1-butyl-3-methylimidazolium octylsulfate, [BMIM][OcSO$_{4}$], has been determined in hydrocarbon (n-hexane, n-heptane, n-octane or n-decane) solutions and alcohol (methanol, 1-butanol, 1-hexanol, 1-octanol or 1-decanol) solutions. Densities and excess molar volumes, V $^{E}$ $_{m}$, have been determined for 1-methyl-3-methylimidazolium methylsulfate, [MMIM][CH$_{3}$SO$_{4}$], solutions with an alcohol (methanol, ethanol or 1-butanol) and with water; for 1-butyl-3-methylimidazolium methylsulfate, [BMIM][CH$_{3}$SO$_{4}$], with an alcohol (methanol, ethanol, 1-butanol, 1-hexanol, 1-octanol or 1-decanol) and with water; and for 1-butyl-3-methylimidazolium octylsulfate, [BMIM][OcSO$_{4}$], with an alcohol (methanol, 1-butanol, 1-hexanol, 1-octanol or 1-decanol) at 298.15 K and atmospheric pressure. The systems exhibit very negative or positive molar excess volumes, V $^{E}$ $_{m}$, and negative or positive excess molar enthalpies, H $^{E}$ $_{m}$, as predicted by the Flory–Benson–Treszczanowicz (FBT) model. Our experimental V $^{E}$ $_{m}$ data were used for the description of H $^{E}$ $_{m}$ for solutions of [MMIM][CH$_{3}$SO$_{4}$] with the alcohols under study. The simple Prigogine–Flory–Paterson (PFP) model, without including the association of the alcohol, gave slightly worse results. Negative molar excess volumes, V $^{E}$ $_{m}$, are attributed to hydrogen bonding between the short chain alcohols and ionic liquid and to efficient packing effects. The FBT model overestimates self-association of the alcohol in the solutions under study and shifts the calculated curves to higher alcohol mole fractions. The thermophysical characteristics of [BMIM][OcSO$_{4}$] were also examined by differential scanning calorimetry (DSC).
