| 摘 要： | 采用鼓泡式平衡釜测定了一异丙醇胺-水、一异丙醇胺-二异丙醇胺以及水-二异丙醇胺等二元体系在65℃、80℃、95℃时的恒温汽液平衡数据。用vanLaar、Margules、NRTL、Wilson、UNIQUAC等5种方程对其进行关联，求出模型参数，利用所得模型参数计算相应的汽相组成，并与实测值比较，二者符合良好。

| Abstract: | The vapor-liquid equilibrium(VLE) data of monoisopropanolamine(MIPA) and water, MIPA and diisopropanolamine(DIPA), and DIPA and water systems were measured at 65 ℃,80 ℃ and 95 ℃ by a bubbling equilibrium still. Five activity coefficient models: Margules, van Laar, Wilson, NRTL, and UNIQUAC, were used to correlate the VLE data of these binary systems to obtain the binary parameters. With these parameters, vapor compositions were calculated and compared with those corresponding experimental data. The results are in good agreement. |
