测定了碳酸二乙酯草酸二乙酯二元体系常压汽液平衡数据,利用二元体系的汽液平衡实验数据,运用VisualBasic计算机语言,采用EOS+γ法分别用Wilson和NRTL方程模拟计算了碳酸二乙酯-草酸二乙酯二元体系在常压下的汽液平衡并进行了关联,其平均偏差分别为0.0309和0.0201,并进行了热力学一致性检验,两种不同模型的计算结果与实验值都较为吻合,其中以NRTL拟合结果为更好。
The equilibrium vapor-liquid equilibrium data of diethyl carbonate diethyl oxalate binary system was measured. Based on the experimental data of the vapor-liquid equilibrium of the binary system, using Visual Basic computer language, EOS + γ method was used to calculate Wilson Diethyl carbonate - diethyl oxalate binary system at atmospheric pressure vapor-liquid equilibrium and associated, the average deviation of 0.0309 and 0.0201, and the thermodynamic consistency test, two different models of the results and The experimental values are more in line with the NRTL fitting results for the better.
