In this work, the mutual solubility of 30 binary systems {aromatic hydrocarbon (1) + ionic liquid (2)} involving benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene as aromatics and the ionic liquids, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, [BMpyr][NTf2], 1-butyl-1-methylpyrrolidinium trifluoromethanesulfonate, [BMpyr][TfO], 1-butyl-1-methylpyrrolidinium dicyanamide, [BMpyr][DCA], butyltrimethylammonium bis(trifluoromethylsulfonyl)imide, [N4111][NTf2], and tributylmethylammonium bis(trifluoromethylsulfonyl)imide, [N4441][NTf2], were determined in the temperature range of T = (293.15 to 333.15) K at p = 0.1 MPa. The influence of the temperature and the structural characteristics of the aromatic hydrocarbons as well as the effect of the structure of the ionic liquids on the phase behavior was analyzed. A comparison between the experimental LLE of the binary systems presented in this work and those found in literature was also carried out. Finally, all the binary systems...
