摘　　要：利用实验数据 ,运用 Visual Basic计算机语言采用 EOS+r法分别用 Wilson,NRTL和 UNIFAC方程模拟计算了草酸二乙酯乙醇二元体系在常压下的汽液平衡。三种不同模型的计算结果与实验值都较为吻合 ,其中以The vaporliquid equilibrium of diethyl oxalateethanol was reproduced through the Visual Basic(VB 6.0) computer language based on Wilson, NRTL and UNIFAC equations. It was found that calculated results of UNIFAC equation were in best agreement with experimental data by comparing the predicted values with measured results.
