摘要
本文将液上气相色谱分析法(HS)推广应用到挥发性相差大的互溶二元系,用自制的采样瓶对水-环丁砜、水-四甘醇(TETRA)两个二元系的液相活度系数(γ)进行了测定,提供了在75.0℃下这两个二元系水的活度系数,并用Wang-Chao 模型对水-环丁砜二元系的实验数据进行了关联,关联后的计算值与实测值能较好地符合.采用Wang-Chao 模型的模型参数,分别对30.0℃及50.0℃水-环丁砜二元系环丁砜的活度系数进行了预测,并与文献数据进行了比较,结果令人满意.
The gas chromatographic headspace analysis method was extended for thedetermination of activity coefficients of the binary systems with very differentvolatility,The activity coefficients of water in aqueous solutions of tetraethy-lene glycol and sulfolane were determined at 75.0℃ over a wide range of molefractions.The determined activity coefficients in aqueous solutions of sulfolanewere reasonably correlated by the Wang-Chao equation.The activity coefficients of sulfolane in water-sulfolane system at 30.0℃and 50.0℃ were predicted and were compared with literature values.Theresults are satisfactory.
