| 摘 要： | 用改进的埃利斯(Ellis)平衡蒸馏器测定了醋酸-醋酸异丙烯酯二元系统在常压下和42.6kPa下的汽液平衡数据。采用Hayden-O'connell缔合模型考察了汽相缔合非理想性,液相采用活度模型Wilson、NRTL方程对测定的数据进行了关联,用非线性最小二乘法回归出二元系统Wilson、NRTL方程参数。汽液相平衡数据经Herington面积法检验满足热力学一致性。

| Abstract: | The VLE data of acetic acid-isopropenyl acetate system were measured using the improved Ellis equilibrium distillation still.Thermodynamic calculations of the experimental data were carried out using Hayden-O'connell method for gas phase and NRTL and Wilson equation for liquid phase.The parameters of NRTL and Wilson models for this binary system were regressed by nonlinear least square method.The VLE data satisfy thermodynamic consistency by Herington method. |
