采用半微量相平衡测定装置和高精度密度-折光率测定仪,精确测定了CsCl-PEG 400-H2O三元体系在15,25和35℃3个温度下不同组分百分比溶液的折光率和密度数据,通过关联密度和折光率数据获得了CsCl在上述温度下的等温溶解度.对饱和体系的溶解度研究表明:在同一温度下CsCl的溶解度随聚乙二醇质量分数的增加而减小;在不同温度下CsCl的溶解度随温度的升高而增大.采用经验方程lnS=A1+A2ω2+A3ω2(2)+A4ω2(3)对饱和体系的溶解度进行了关联,效果较好.对不饱和体系的研究表明:当盐含量一定时,随着醇水比例的增加,体系的密度不断增大,折光率也随盐含量增加而增大;当醇水质量比一定时,体系的密度和折光率随盐含量的增加而增大,对不饱和体系的密度和折光率用经验方程Y=(A0+A1ω2+A2ω1+A3ω1ω2+A4ω2ω1(2))×exp[A5(ω1/ω3)+A6(ω1/ω3)2]进行拟合,拟合效果较好,同时给出了体系的盐析率曲线.本研究不仅为溶液化学提供了基础数据,也为混合溶液中盐和醇的分离纯化提供一种新的方法和思路,对CsCl进一步的应用、开发和研究具有一定的参考价值.
