ABSTRACT
Following the importance of equilibrium data of biomass components as well as octane boosters, the isothermal vapor-liquid behaviors of binary and ternary systems including hexane, toluene, and anisole, and ternary system of methyl tert-butyl ether, hexane, and toluene were investigated at 313.2 K. To do so, the Othmer still was employed to collect the experimental data. Furthermore, thermodynamic calculations were implemented by the Peng-Robinson equation of state and UNIQUAC and NRTL activity coefficient models. The whole binary systems passed the isothermal thermodynamic consistency test of Herington. Based on the obtained results, no azeotrope was observed. Moreover, the obtained errors of calculation imply that UNIQUAC equation is suitable for the representation of the vapor and liquid phases compositions.
