Abstract�� The atmospheric vapor-liquid equilibrium(VLE) data of acetone-isopropenyl acetate binary system were measured by using the improved Ellis equilibrium distiller.Thermodynamic calculation of the experimental data were carried out by using ideal equation for gas phase and using NRTL and Wilson equation for liquid phase.The parameters of NRTL and Wilson model for this binary system were regressed by nonlinear least square method,and the calculated data from Wilson model accorded well with the experimental data.The VLE data were tested by Herrington method and showed satisfying thermodynamic consistency.
