摘　　要：用改进的Rose釜测定了常压下H2O+HAc+甲基叔丁醚三元体系部分汽液平衡数据,借助实验数据,利用AspenPlus软件对该三元体系NRTL和UNIQUAC方程的模型参数进行了回归。回归结果反过来用于汽液平衡的数学模拟,结果表明实验数据与模拟结果很吻合,该结果可以为相关研究及工业设计提供帮助。Vapor-liquid equilibrium data of the water ＋ acetic acid ＋ methyl tert-butyl ether at atmospheric pressure was measured using an improved Rose still. The data were used to recover the parameters of the NRTL and UNIQUAC models. Aspen Plus was adopted to simulate the vapor-liquid equilibrium of the water ＋ acetic acid ＋ methyl tert-butyl ether. It is shown that the experimental data agree very well with the simulated results.
