| 摘 要： | 本文使用LKB-2107型流动式微量热计测量了在293.15K、298.15K、303.15K和常压下部分互溶体系4甲基2戊醇和水的过量焓,并将所得结果用Rcdlich-Kister方程关联. 富醇区数据还用NRTL模型进行了关联,并推算出常压下汽液平衡数据.推算值与实验值比较,汽相组成和泡点的平均偏差分别为0.02摩尔分率和1.03K.

| Abstract: | Excess enthalpies of partially miscible system 4-methyl-2-pentanol+ water are measured with LKB 2107 Flow Microcalorimeter at 293.15K,298.15K 303.15K under normal pressure. The results obtained are fitted with Redlich-Kister equation. The data measured in the rich alcohol region are correlated with NRTL model and vapour liquid equilibrium (VLE) data under normal pressure are predicted. Mean deviations between vapour compositions and bubble points of VLE experimental values and predicted values are 0.02 mole fraction and 1.03K respectively. |
