Liquid-liquid equilibria for the three systems methanol-ethyl ether-cyclohexane, methanoltetrahydrofuran-cyclohexane, and methanol-methyl acetate-cyclohexane were measured at 25°C. For these systems, the applicability of the extended Kretschmer-Wiebe equation was examined by taking account of both the self-association of methanol and the association of unlike molecules between methanol and polar solvents. For methanol ethyl ether cyclohexane system, experimental data gave reasonable agreement with the binodal curve calculated by use of the parameters obtained from binary data alone. For the other two systems, the agreement between experimental and calculated binodal curves were not satisfactory. The NRTL equation was also utilized to calculate the ternary liquid-liquid equilibria from the constituent binary data, but it failed to represent the experimental solubility data.
