AB In this work, mutual solubilities of 24 binary mixtures containing ionic liquids (1-ethyl-3-methylpyridinium ethylsulfate, 1-ethyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide,1-hexyl-3-methylimidazolium dicyanamide and 1-propyl-3-methylpyridiniumbis(trifluoromethylsulfonyl)imide) with aromatic hydrocarbons (benzene, toluene, ethylbenzene,o-xylene, m-xylene and p-xylene) were determined in the range T = (293.15–333.15) K and at atmosphericpressure, and the corresponding temperature-composition phase diagrams were obtainedfrom the density of the equilibrium phases. From the experimental data, the effect of the structureof the ionic liquid and the aromatic hydrocarbon on the solubility was analyzed and discussed.The ionic liquids reported in this work show a negligible solubility in the studied aromatic hydrocarbonsand the solubility of the aromatic compounds in the ionic liquids decreases in the orderbenzene > toluene > ethylbenzene > xylene isomers. The experimental results show that solubility isalso affected by the ionic liquid structure while the temperature has a very little effect on the phaseequilibria. Finally, experimental liquid–liquid equilibrium data were satisfactorily correlated using theNon-Random Two-Liquid (NRTL) model.
