Liquid–liquid equilibrium for the quaternary system water+tetrahydrofuran+n-heptane+butyl acetate mixture at 25°C and atmospheric pressure

In this work, the experimental liquid–liquid equilibrium (LLE) data were measured for quaternary mixtures of eugenol(1) + β–caryophyllene(2) + 1-propanol(3) + water(4) at temperatures 303.15, 313.15, and 323.15 K and at atmospheric pressure. The equilibrium data ware determined by using an equilibrium cell with temperature controlled. Quantitive analysis was performed by using gas chromatography (GC) equipped with thermal conductivity detector and capillary column Rtx-5. The experimental data were then correlated by using the NRTL and the UNIQUAC models. The reliability of these models were tested by compared with the experimental results using a root mean square deviation (RMSD). Based on the RMSD, the NRTL and the UNIQUAC models suited really well and give satisfactory result for the system of eugenol, β–caryophyllene, 1-propanol, and water with the average RMSD of the UNIQUAC and the NRTL models were 0.417% and 0.502%, respectively. Furthermore there was no significant effect of temperatures on the equilibrium composition for the system.
