摘要
用液 液平衡釜测定了常压和 5 8 8℃下正庚烷 苯 N 甲酰吗啉 (NFM )、甲基环己烷 苯 NFM、正庚烷 甲苯 NFM和甲基环己烷 甲苯 NFM 4组三元体系的液 液平衡数据。用NRTL和UNIQUAC模型进行了关联 ,求得了它们的褶点 ,并对NFM溶剂存在下烷烃相对于芳烃的选择性进行了比较。
Liquid liquid equilibrium data for the ternary systems of heptane benzene NFM, heptane toluene NFM, methylcyclohexane benzene NFM and methylcyclohexane toluene NFM were measured at 58 8 ℃ under atmospheric pressure. The experimental results of all ternary liquid liquid equilibrium data were correlated by the NRTL and UNIQUAC models. The plait point data of all ternary systems were determined. Selectivities of aromatics and alkane in the extract phase were compared. The obtained thermodynamic data can provide useful information for aromatic recovery applications.
