Mixtures of cyclohexyl acetate and cyclohexanol were used as a mixed solvent to study liquid-liquid equilibria (LLE) of the acetic acid-water-cyclohexanol-cyclohexyl acetate quaternary system. The solubility diagram and tie-line data were determined at 298±0.20 K and atmospheric pressure, using various compositions of mixed solvent. Reliability of the data was ascertained by making Othmer-Tobias and Hand plots.
