Influence of temperature on liquid - liquid equilibrium of methanol + toluene + hexane ternary system at atmospheric pressure

Abstract

Abstract Liquid-liquid equilibrium of methanol + toluene+ hexane ternary system at 278.15,283.15, 288.15 and 293.15 K are reported. The effect of the temperature on liquid-liquidequilibrium is discussed. All chemicals were quantified by gas chromatography using athermal conductivity detector. Experimental data for the ternary system are compared withvalues calculated by the NRTL and UNIQUAC equations. It is found that the UNIQUACequation fitted to the experimental data is more accurate than the NRTL model for thisternary system for all temperatures studied.
