摘要: 本文采用改进的静态法平衡釜测定了甲苯-环丁砜二元体系在30℃、35℃、40℃、45℃、50℃、55℃、60℃、65℃、70℃、九组恒温下的总压-液相组成(P-x)数据,采用间接法计算了汽相组成(y)及Q函数.并分别用Wilson方程和NRTL方程对九组不同温度下的汽液平衡数据进行了关联,获得比较满意的结果.

Abstract: Isothermal total pressure-composition data for binary system toluene-sulpholane at 30℃,35℃,40℃,45℃,50℃,55℃,60℃,65℃ and 70℃ have been determined by a modified static equilibrium still. The equilibrium vapor composition and (Qfunction (GB/RT) were calculated by an indirect method. Using the Wilson and NRTL equations to correlate the vapor-liquid equilibrium data, resulted in good agreement between calculated values and experimental data.
