摘要
用鼓泡平衡釜在不同温度下测定了苯－噻吩－ＤＭＦ（Ｎ，Ｎ－Ｄｉｍｅｔｈｙｌｆｏｒｍａｍｉｄｅ，二甲基甲酰胺）体系的二元和三元体系的汽液平衡（ＶＬＥ）数据，所测数据均通过热力学一致性检验，并用多种模型作了关联，其结果令人满意。根据Ｃｏｎｄｅｒ和Ｐｕｒｎｅｌｌ提出的有限浓度普遍化保留理论导出了有限稀释活度系数工作方程，用色谱仪测定了苯－ＤＭＦ和噻吩－ＤＭＦ两个二元体系在稀浓度区的活度系数，结果证明在全浓度范围内Ｗｉｌｓｏｎ模型对本研究体系是完全适用的。
The vapour liquid equilibrium data of three binary systems benzene-DMF,thiophene-DMF and benzene-thiophene,and a ternary system benzene-thiophene-DMF were experimentally measured,the results were correlated with various thermodynamic models, it shows that the Wilson model fits the VLE data for benzene-thiophene-DMF system in whole concentration range well.
