水-甲基叔丁基醚-二异丙醚三元体系液液相平衡的研究

Ternary Liquid-liquid Equilibrium for Mixtures of Water, Methyl Tert-butyl Ether and Diisopropyl Ether

在常压下测定了不同温度时水-甲基叔丁基醚-二异丙醚三元体系的液液平衡,并用ModifiedUNIQUAC模型和ExtendedUNIQUAC模型对所测体系进行了关联计算,ModifiedUNIQUAC模型的计算结果与实验数据的关联性更好。

Ternary liquid-liquid equilibrium data for the water, methyl tert-butyl ether and diisopropyl ether were measured at different temperatures and ambient pressure. The experimental ternary liquid-liquid equilibrium data had been satisfactorily correlated by using the modified UNIQUAC and extended UNIQUAC models. The calculated results using the modified UNIQUAC model were better compared with the experimental data.
