摘要
采用改进的Ｒｏｓｅ釜测定了１０１．３ｋＰａ下苯（１）－ＤＭＦ（２）、甲基环己烷（１）－苯（２）、甲基环己烷（１）－ＤＭＦ（２）３组二元体系及甲基环己烷（１）－苯（２）－ＤＭＦ（３）三元体系的汽液平衡数据。三组二元体系的ＶＬＥ数据均通过了微分法热力学一致性检验。应用ＮＲＴＬ模型和ＵＮＩＱＵＡＣ模型关联了二元、三元体系的ＶＬＥ数据。推算了三元体系ＶＬＥ数据。
apor-liquid equilibrium (VLE) data for the binary systems of benzene (1 )-DMF (2 ),metylcyclohexane (1 )-benzene (2 ), methylcyclohexane (1 )--DMF (2') and the ternary system of methylcyclohexane (l )--benzene (2 )-DMF (3) were measured at 101. 3 kpa by a modified Rose still. Thermodynamic consistency of the binary VLE data was tested by the differential method.The experimental results of these binary and ternary VLE data were correlated and estimated by the NRTLand UNIQUAC models.
