摘要

本文用液-液平衡测定装置在常压与50℃下

测定了水-乙酸乙酯-乙酸和水-乙酸丁醋-乙酸两组三元物系的液-液平衡数据

和文献数据作了比较.并用NRTL、LEMF、UNIQUAC、UNIFAC活度系数方程进行了关联.将实验数据与关联结果比较

获得了满意的结果.对于乙酸丁酯三元物系

以LEMF方程拟合精度较好;对于乙酸乙酯三元物系

以NRTL方程为最佳.

Abstract

Liquid-liquid equilibrium data for the ternary systems

water-ethyl acetate-acetic acid and water-butyl acetate-acetic acid have been determined under atomospheric pressure and at 50℃. The experimental LLE data were compared withthose in the literature and correlated with NRTL

LEMF

UNIQUAC and UNIFAC equations. Reaults calculated with these equations showed that LEMF equation fits better for the butyl acetate ternary system

and that NRTL equation fits best for the ethyl acetate ternary system.
