【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-PrCl313%HCl-H2O (25 ℃ ) and CsCl-PrCl3-42%HAc-H2O (30℃ ) were studied and the corresponding equilibrium diagram was constructed. Two compounds CsCl. PrCl3. 6H2O and3CsCl. PrCl3. 7H2O were found in each system. It is indicated that the effects of HCl andHAc on the system CsCl-PrCl3-H2O are the same. Wang Hong’s interpretation to Meyer’ Sreaction was verifled and the relevant properties of the compounds were also investigated.
