The liquid-liquid equilibrium (LLE) data for a ternary system {methyl eugenol + linalool + 1-ethyl-3-methylimidazolium hydrogen sulfate [EMIM][HSO4]} (Meu-Lin-IL) were measured at 298.2 K and atmospheric pressure. The Othmer-Tobias correlation was used to verify the reliability of the experimental tie-line data. The solubility curves were obtained using the cloud point titration indicating the liquid-liquid equilibrium of the ternary system was in Type II class where two immiscible curve pairs were attained. Distribution coefficients, separation factors and selectivity were calculated for the immiscibility regions. The calculated results were compared with the experimental data. Characterization studies were performed by Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA) and proton nuclear magnetic resonance spectroscopy (H-1-NMR) techniques.
