| 摘 要： | 用改进的Rose平衡釜测定了等压 (0 .10 13MPa)下五个二元体系 (乙醇 水、叔丁醇 水、乙醇 叔丁醇、乙基叔丁基醚 乙醇、叔丁醇 乙基叔丁基醚 )和一个四元体系 (水 乙醇 叔丁醇 乙基叔丁基醚 )的汽液相平衡数据。用UNIFAC基团贡献法预测了上述五个二元体系及一个四元体系的汽液相平衡 ,预测结果与实验数据吻合较好。

| Abstract: | The data of vapor liquid equilibrium were measured with a modified Rose equilibrium still under isopiestic pressure (0.1013MPa) for the five binary systems including ethanol water,tert butyl alcohol water,ethanol tert butyl alcohol,ethyl tert butyl ether ethanol,tert butyl alcohol ethyl tert butyl ether respectively and a quaternary systems of water ethanol tert butyl alcohol ethyl tert but yl ether.The UNIFAC model was used to calculate the vapor liquid equilibrium of the above six systems,the predicted results agreed well with the experimental data. |
