Ternary liquid-liquid equilibria for the mixtures (1-methyl-3-octylimidazolium chloride + an alkanol + an alkane) at 298.2 K are reported. The alkanes used were heptane, dodecane, and hexadecane, and the alkanols were methanol and ethanol. The solubility of the alkanol is higher in the ionic liquid rich phase than in the alkane rich phase. The effectiveness of extracting an alkanol from mixtures containing an alkane using the solvent 1-methyl-3-octylimidazolium chloride is discussed in terms of the ratio of the solubilities in the two phases. The NRTL equation was used to correlate the experimental tie lines. There are no data in the literature for the mixtures discussed in this paper.
