| 摘 要： | 用改进的Ｏｔｈｍｅｒ汽液平衡釜在０．１０１３ＭＰａ下测定了乙醇水氯化钙、醋酸钾体系在恒盐摩尔分率下的汽液平衡数据。用Ｆｕｒｔｅｒ方程、修正的Ｆｕｒｔｅｒ方程、拟二元模型及溶剂化模型对实验数据进行关联，取得良好结果，其中乙醇水氯化钙体系实验数据用修正的Ｆｕｒｔｅｒ方程关联，所得汽相平均偏差为０．０１２４。

| Abstract: | Isobaric VLE data at 0.0103 MPa were measured for the systems EtOH H 2O with CaCl 2 and KAc under fixed salt mole fraction using a modified Othmer recirculation still. A modified Furter equation to correlate salt effect was proposed. The VLE data measured were correlated by Furter Eq., the modified Furter Eq., Three Parameters method, and Ohe's model. Using the modified Furter equation, the mean deviation of vapor composition for the system EtOH H 2O with CaCl 2 was 0.0124. |
