Abstract

The liquid-liquid equilibrium (LLE) data of ternary Eugenol + Isobutanol + H2O and β-Caryophyllene + Isobutanol + H2O systems were measured at temperatures of 303.15 K and 323.15 K. Equilibrium cell with water jacket for keeping the temperature was used. Equilibrium data were obtained by stirring the mixture for 4 hours and settled for 20 hours to allow the system reach the equilibrium state. Samples of organic and aqueous phases were analyzed using Gas Chromatography. All the measured data were correlated using NRTL and UNIQUAC models. The reliability of the models is tested by comparison of calculated equilibrium compositions with experimental data in terms of root mean square deviations (RMSD). The system exhibited type II phase behaviour from immiscible area. It has two pairs miscible components (Eugenol + Isobutanol and β-Caryophyllene + Isobutanol), two pairs partially miscible components (Eugenol + H2O and Isobutanol + H2O) and one pair immiscible components (β-Caryophyllene + H2O). The temperatures on this system have small effect on immiscible zone and slope of tie lines. Based on experiment and calculation results, Eugenol + Isobutanol + H2O system has been successfully represented slightly better using UNIQUAC model with average values of RMSD is 2.0842% meanwhile NRTL model has higher value of RMSD that is 2.1359%, and β-Caryophyllene + Isobutanol + H2O system has been successfully represented better using UNIQUAC model with average values of RMSD is 2.1521% meanwhile NRTL model has higher value of RMSD that is 3.2976%.
