摘要 在101.32 kPa下,用改进的Othmer釜测定了甲醇-碳酸二甲酯二元物系的等压汽液平衡数据。利用UNIFAC模型对实验数据进行了拟合,得到了新基团—OCOO—与—CH_3—,CH_3OH基团间的UNIFAC作用参数,扩充了UNIFAC模型的应用范围。与原始基团划分的UNIFAC模型关联结果相比,采用新基团划分法推算得到的汽液平衡数据与实验值偏差更小,说明新基团划分更合理,并利用拟合的参数对含有碳酸酯物系的汽液平衡进行了验证。 在101.32 kPa下,用改进的Othmer釜测定了甲醇-碳酸二甲酯二元物系的等压汽液平衡数据。利用UNIFAC模型对实验数据进行了拟合,得到了新基团—OCOO—与—CH<sub>3</sub>—,CH<sub>3</sub>OH基团间的UNIFAC作用参数,扩充了UNIFAC模型的应用范围。与原始基团划分的UNIFAC模型关联结果相比,采用新基团划分法推算得到的汽液平衡数据与实验值偏差更小,说明新基团划分更合理,并利用拟合的参数对含有碳酸酯物系的汽液平衡进行了验证。
