| 摘 要： | 利用气相色谱法测定了常压下30℃、40℃和50℃时甲苯 正庚烷 (四甘醇+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模型对所测液液相平衡数据进行了热力学关联,用单纯型优化法求出了相应的模型参数。用该模型对本体系进行了预测,取得了令人满意的结果。

| Abstract: | Liquid-liquid equilibrium (LLE) data of toluene-n-heptane-tetraethylene glycol and triethylene glycol system at 30 ℃,40 ℃ and 50 ℃ were determined at the atmospheric pressure by gas chromatography. The quantitative analysis was based on the normalization of peak area percent, and the accurate results were acquired. The NRTL model was used to correlate and predict the LLE data of system and obtained the mode′s parameters by using of simplex method. The agreement between calculated and experimental data was satisfactory. |
