正庚烷-甲苯-含水四甘醇多元系液-液相平衡数据的测定与预测

LIQUID-LIQUID EQUILIBRIUM OF n-HEPTANE-TOLUENE-TETRA-WATER SYSTEM

本文提供了正庚烷-甲苯-含水四甘醇多元系统在温度为60、100℃,四甘醇含水量为3、5m%的条件下三组液-液相平衡数据。同时,采用UNIQUAC 模型从二元数据对该体系及正庚烷-苯-含水四甘醇体系多元液-液相平衡进行了预测。

Quarternary liquid-liquid equilibrium data have been measured for the system of n-heptane- toluene-TETRA(glycol)-water at 60 and 100℃ with water content in TETRA of 3 and 5m%.The tie-line data of this system and n-heptane-benzene-TETRA-water system in literature[1]were pre- dicted with UNIQUAC model from binary phase equilibrium data.
