摘　　要：测定了碳酸二乙酯 -乙醇二元体系的汽液平衡数据 ,利用二元体系的汽液平衡数据 ,采用EOS +γ法分别用Wilson和NRTL方程模拟计算了碳酸二乙酯 -乙醇二元体系在常压下的汽液平衡并进行了关联 ,二种不同模型的计算结果与实验值都较为吻合 。The atmospheric vapor-liquid equilibrium(VLE) system of diethyl carbonate-ethanol was reproduced through the Visual Basic(VB6.0) computer language by using the Wilson equation and the NRTL equation. The results of the two methods are all that could be desired. It was found that calculated results of Wilson equation were in the better agreement with experimental data.
