Ternary Liquid-Liquid Equilibrium for Eugenol plus tert-Butanol plus Water System at 303.15 and 323.15K and Atmospheric Pressure

The objective of this study was to determine ternary liquid-liquid equilibrium for eugenol + tert-butanol + water system at 303.15 and 323.15K and atmospheric pressure using 25 mL equilibrium cell equipped with jacketed water connected to water bath in order to maintain equilibrium temperature at a constant value. The procedure of this experiment was conducted by inserting mixture of eugenol + tert-butanol + water system with certain composition into equilibrium cell. The solution was stirred for 4 hours and then was allowed for 20 hours in order to separate aqueous and organic phases completely. At equilibrium condition, the temperature of equilibrium cell was recorded as equilibrium temperature at atmospheric pressure for each measurenment. The equilibrium compositions of each phase were analyzed using Gas Chromatography. The experimental data obtained in this work were correlated with NRTL and UNIQUAC equations giving root mean square deviation between esperimental and calculated equilibrium compositions of 0.03 and 0.04, respectively.
