Liquid–liquid equilibrium (LLE) data for the ternary systems (heptane + p-xylene + 1-ethyl-3-methylpyridinium ethylsulfate) and (n-octane + p-xylene + 1-ethyl-3-methylpyridinium ethylsulfate) were measured at T = 313.15 K and atmospheric pressure. The selectivity and aromatic distribution coefficients, calculated from the equilibrium data, were used to determine if this ionic liquid can be used as a potential extracting solvent for the separation of p-xylene from heptane and n-octane. The consistency of tie-line data was ascertained by applying the Othmer–Tobias and Hand equations.
► This paper reports the LLE data of ternary systems {aliphatic compounds (1) + p-xylene (2) + [EMpy][ESO4] (3)}. ► The distribution coefficient and the selectivity were obtained from the experimental data. ► The consistency of LLE data was successfully correlated with Othmer–Tobias and Hand equations.
