摘　　要：采用液上气相色谱法测定了CO气相催化偶联制草酸二乙酯产物中有关的六组二元物系的等温汽液平衡数据。选用Wilson、NRTL、UNIQUAC活度系数方程关联了实验数据。The vapor liquid equilibrium data for six binary systems concerned with the preparation of Diethyl Oxalate by Vapor Phase Catalytic Reaction of CO at constant temperature are determined by using Headspace Gas Chromatography. The experimental data are correlated by Wilson, NRTL and UNIQUAC equations. The calculated results are consistent with the experimental data.
