Abstract

Liquid–liquid equilibria of the methanol + toluene + methylcyclohexane ternary system at 278.15, 283.15, 288.15, 293.15, 298.15 and 303.15 K are reported. The effect of the temperature on liquid–liquid equilibrium is discussed. Data for the ternary system is available from the literature at T = 298 K. All chemicals were quantified by gas chromatography using a thermal conductivity detector. Experimental data for the ternary system are compared with values calculated by the NRTL and UNIQUAC equations. It is found that the UNIQUAC and NRTL models provide similar good correlations of the solubility curve at these six temperatures.
