烷烃-芳烃-N-甲酰吗啉体系液液平衡

STUDY OF LIQUID LIQUID EQUILIBRIUM FOR ALKANE AROMATICS N FORMYLMORPHOLINE SYSTEM

用液液平衡釜测定了等温下正庚烷苯ＮＦＭ、甲基环己烷苯ＮＦＭ、正庚烷甲苯ＮＦＭ和甲基环己烷甲苯ＮＦＭ等４组三元体系的液液平衡数据，用ＮＲＴＬ和ＵＮＩＱＵＡＣ模型进行了关联，求得各三元体系的褶点数据，并对ＮＦＭ溶剂存在下烷烃和芳烃的选择性进行了比较。

Isothermal liquid liquid equilibrium(LLE) data for the ternary systems of heptane benzene NFM、heptane toluene NFM、methylcyclohexane benzene NFM and ethylcyclohexane toluene NFM were measured at normal pressure.The experimental results of all ternary LLE data were correlated by the NRTL and UNIQUAC models.The plait point data of all ternary systems were determined . Selectivity of aromatics and alkane in the extract phase have been compared .
