摘要： 测定了四元体系CsCl-PrCl3-13%HCl-H2O(25℃)和CsCl-PrCl3-42%HAc-H2O(30℃)的稳定平衡态的溶度数据,绘制了相应的溶度图.两个体系中皆有4种固相:CsCl、PrCL3·6H2O2种原始盐和CsCl·PrCl·6H2O、3CsCl·PrCl3·7H2O2种复盐.证实了文献中对Meyer反应1机理的解释,并对新相进行了热分析、X射线粉末衍射及偏光显微镜测定.

Abstract: The solubillties of the saturated solution of the quaternary system: CsCl-PrC13-13%HCl-H2O (25 ℃) and CsCl-PrC13-42% HAc-H2O (30℃) were studied and the corresponding equilibrium diagram was constructed.Two compounds CsCl.PrC13.6H2O and 3CsCl.PrC13.7H2O were found in each system.It is indicated that the effects of HCl andHAc on the system CsCl-PrC13-H2Oare the same.Wang Hong's interpretation to Meyer' Sreaction was verifled and the relevant properties of the compounds were also investigated.

Key words: Quaternary system, Meyer'S reaction, Prasedymium chloride, Cesium chloride
