Liquid-liquid equilibrium (LLE) data for the ternary systems {hexane + o-xylene + 1-ethyl-3-methylpyridinium ethylsulfate}, {hexane + p-xylene + 1-ethyl-3-methylpyridinium ethylsulfate}, and (hexane + m-xylene + 1-ethyl-3-methylpyridinium ethylsulfate) were determined at T=298 15K and atmospheric pressure. Selectivity. percent removal of aromatic, and solute distribution ratio. derived from the experimental equilibrium data, were used to determine if this ionic liquid can be used as a potential extracting solvent for the separation of xylenes from hexane. The consistency of tie-line data was ascertained by applying the Othmer-Tobias e
