| 摘 要： | 用改进的埃利斯(Ellis)平衡蒸馏器测定了丙酮-乙酸异丙烯酯二元系统在常压下的汽液平衡数据,用液相活度模型Wilson、NRTL方程对测定数据进行关联,采用非线性最小二乘法回归出二元系统在常压下的Wilson、NRTL方程参数,Wilson模型与试验值符合良好.汽液相平衡数据经Herrington面积法检验满足热力学一致性.

| 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. |
