摘　　要：用改进的Ｏｔｈｍｅｒ汽液平衡釜测定了０．１０１３ＭＰａ下异丙醇－水－乙酸钾体系在恒盐摩尔分率下的汽液平衡数据。用Ｆｕｒｔｅｒ方程、Ｍｉｔｓｕｈｏ方程、修正的Ｆｕｒｔｅｒ方程和溶剂化模型对实测数据进行了关联，其中修正的Ｆｕｒｔｅｒ方程关联结果较好，汽相组成平均偏差为０．０１０２。Isobaric VLE data under 0 0103 MPa were measured for the systems 2 PrOH H 2O with KAc under fixed salt mole fraction using a modified Othmer recirculation still The VLE data measured were correlated by Furters equation,Mitsuhos equation,the modified Furters equation,and Ohes model Using the modified Furters equation,the mean deviation of vapor composition for the system 2 PrOH H 2O with KAc was 0.0102
