摘要
利用双循环汽液平衡釜测定 10 1.3kPa下异戊醇 乙二醇体系的汽液平衡数据x y t,并运用该实验结果 ,进一步获得组分的液相活度系数。实验数据经Herrington方法检验 ,表明符合热力学一致性。用Wil son模型对该实验数据进行处理 ,计算结果与实验值的平均绝对偏差为 0 .0 0 6 3,取得满意的效果。
Isobaric vapor liquid equilibrium under 101.3kPa for the system of isopentanol and ethylene glycol was measured by use of a recalculating still.The activity coefficients of the system were determined further.Vapor liquid equilibrium data for the binary system passed the thermodynamic consistency check.The activity coefficients were correlated with the Wilson equation,and the results were in perfect agreement with experimental values.
