ABSTRACT
Isobaric vapor liquid equilibrium (VLE) data for the hexamethyl disiloxane + isopropyl acetate system at atmospheric pressure (101.3 kPa) were measured. The thermodynamic consistency of experimental data was checked with the Herrington method. The experimental binary data were correlated with Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) two-parameter models. All three models satisfactorily fitted with the experimental data and the Wilson model was the most suitable one to represent the VLE data. The result showed that the standard deviations of the Wilson model in temperature and vapor phase were 0.2279 and 0.0568, respectively. The system presents a minimum temperature azeotrope at 361.12 K with the mole fraction of hexamethyl disiloxane as 0.1572.
