Liquid-liquid equilibria (LLE) of the binary system of methanol-cyclohexane were measured in the range of 277.79-317.94 K. LLE of two ternary systems, methanol-cyclohexane including either one of cyclic ethers of 1,3-dioxolane and 1,4-dioxane, were also measured at the temperatures of 277.79, 288.54, 298.63 and 308.64 K. Two liquid phase regions of the ternary systems were found in the range 0.2-0.04 mole fraction of the ethers, which were smaller than those of the ternary systems of methanol-heptane including the ethers of 0.35 to 0.1 mole fraction studied before. The results were successfully correlated with the UNIQUAC equation by minimizing an objective function with weighting factors.
