【摘要】 本文在600×1.333×10~2Pa和400×1.333×10~2Pa压力下分别测定了甲苯-苯甲醛-苯甲酸三元体系及其三个二元体系的汽液平衡数据。用点检验法对二元数据进行了热力学一致性检验,并用Margules、wilson、NRTL和UNIQUAC方程作热力学关联。预测了三元汽液平衡关系,与实测值吻合结果令人满意。更多还原

【Abstract】 VLE data have been measured for the ternary system toluene-benzaldehyde-benzoic acid and for their binary system at 600×1. 333×10~2 Pa and 400×1. 333×10~2 Pa. These data for binary system have been tested for thermodynamic consistency by the differential method, and correlated with the Margules, Wilson, NRTL, UNIQUAC equations. These equations except the first can be used to estimated the VLE for the ternary system, and predicted results are in agreement with experimental data.更多还原
