| 摘 要： | Vapor-liquid equilibrium data of hexamethyl disiloxane ＋ vinyl acetate system at 101.3kPa were meas- ured by using double circulating vapor-liquid equilibrium still. The thermodynamic consistency of the VLE data was examined by Herrington method. Experimental data was correlated by non-random two-liquid （NRTL）, Wilson and universal quasichemical （UNIQUAC） parameter models. All the models satisfactorily correlated with the VLE data. The result showed that the NRTL model was the most suitable one to represent experimental data satisfactorily. The system had a minimum temperature azeotrope at 345.71 K and the mole azeotropic composition was 0.0541.
