摘要:

实验测定了二氧化碳和碳酸二甲酯(DMC)二元体系的高压气液相平衡数据. 实验温度为333.0 到393.0 K, 实验压力为3.98 到13.75 MPa. 应用Peng-Robison (PR)立方形状态方程和van der Waals-1 混合规则对实验数据进行了关联计算, 同时得到了二元相互作用参数. 计算结果与实验数据具有很好的一致性.

Abstract:

High pressure vapor-liquid equilibrium data for the carbon dioxide + dimethyl carbonate (DMC) binary system were measured at four temperatures in the 333.0 to 393.0 K range and under pressures ranging from 3.98 to 13.75 MPa. The experimental data were correlated with the Peng-Robison (PR) cubic equation of state and the van der Waals-1 mixing rule. The binary interaction parameters were also obtained. The agreement between experimental results and calculations was good.

Key words: Vapor-liquid equilibrium, High pressure, Binary system, Carbon dioxide, Dimethyl carbonate
