It was suggested in papers published by other authors that the investigated ionic liquid could potentially be a suitable solvent for extracting aromatic compounds from mixtures containing aliphatic hydrocarbons, such as naphtha cracker feeds. To be able to assess the selectivity of 1-ethyl-3-methylimidazolium ethylsulfate towards aliphatic, cyclic, and aromatic hydrocarbons, mutual solubilities of the ionic liquid and n-heptane, methylcyclohexane, and toluene were measured by the volumetric method. To evaluate quantitatively the quality of the experimental data and their agreement with available literature values, a correlation by two polymer-solution models, the modified Flory-Huggins equation proposed by de Sousa et al. and the thermodynamic lattice model proposed by Qin and Prausnitz was carried out, the model parameters being optimized by a gnostic regression method.
