摘要
用气相单循环的玻璃平衡釜测定了碳酸二甲酯-草酸二甲酯二元系统的常压汽液相平衡数据，用积分法对其进行了热力学一致性检验。回归得到了草酸二甲酯的Antoine方程参数。用Wilson活度系数方程对实验数据进行了关联, 取得了较好的结果。
The isobaric vapor-liquid equilibrium data of the binary system dimethyl carbonate-dimethyl oxalate was measured by using a vapor-recycled vapor-liquid equilibrium still. Integral method was used to examine the thermodynamic consistency. The constants of Antoine equation for dimethyl oxalate were correlated by the data from literature. The activity coefficient of the liquid phase was correlated by the Wilson equation and satisfactory correlation result of the experimental data was obtained.
