| 摘 要： | 利用气相色谱法测定了常压下２５℃、４０℃和５０℃时正庚烷－甲苯－三甘醇体系的液－液相平衡数据，采用峰面积归一化法定量，所得数据准确、可靠。用ＮＲＴＬ模型对所测数据进行了热力学关联，求出了相应的模型参数。用该模型对本三元体系进行了预测，结果令人满意。

| Abstract: | Liquid liquid equilibrium(LLE) data of toluene n heptane triethylene glycol of ternary system at 25 ℃,40 ℃ and 50 ℃ are determined under atmospheric pressure by gas chromatography The quantitative analysis is based on the normalization of peak area %,and accurate results are obtained The NRTL model is used to correlate and predict the LLE data of the system and to obtain the models parameters at 25 ℃,40 ℃ and 50 ℃ The agreement between calculated and experimental data is satisfactory |
