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。

关 键 词:三甘醇  甲苯  正庚烷  液液平衡  关联  预测

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 models parameters at 25 ℃,40 ℃ and 50 ℃ The agreement between calculated and experimental data is satisfactory
Keywords:triethylene glycol  toluene   n heptane  liquid liquid equilibrium  correlation  prediction
