摘要

测定了由正丁醇、水和醋酸丁酯形成的三元物系及部分互溶二元物系在20℃、30℃和40℃的LLE(液液平衡)数据

并与文献中已有的正丁醇-水的LLE实测数据核对

说明了测定方法的可靠性.用NRTL和UNIQUAC方程分别进行了三元和二元LLE数据的关联和预测.根据溶液热力学特性对二元LLE模型参数进行了鉴别.在三元LLE数据的关联中

对两种目标函数(摩尔分数和分配系数)进行了比较

并对前一种目标函数中的权重取值问题进行了考察.通过对部分互溶二元物系参数的评选

提高了利用二元参数对三元物系进行预测的准确度.

Abstract

LLE (liquid-liquid equilibria) data have been determined for the n-butyl alcohol-water-butyl acetate ternary system and the related binary systems at20℃

30℃ and 40℃. The experimentally determined LLE data for the n-butyl alcohol-water binary system have been found to be in satisfactory agreement with available literature data. The correlation and prediction of the LLE data have been done by using NRTL and UNIQUAC models. The model parameters of binary systems have been identified with a thermodynamic criterion. In the correlation of ternary LLE data

two objective functions (mole fraction and distribution constant) have been used for purpose of comparison. The effect of weighting in the first objective function has been examined. In predicting the ternary LLE with different sets of parameter values obtained for each of the constitutent binary systems

improved prediction results have been obtained by comparing the results of different combinations of the sets of parameter values and choosing those giving the best results.
