摘要： 用改进了的半微量相平衡方法研究了Pr(NO3)3·4H2O-18C6-CH3COCH3三元体系在18℃时的溶解度,所得相图实际上仅由一条溶解度曲线组成,与它相对应的固相组成为Pr(No3)3·18C6·4H2O。用不同方法对配合物中水的稳定性做了考查。借助于偏光显微观察等手段考查了配合物的差热与热重分析过程,提出了配合物的分解机理。

Abstract: The solubilities of the Pr(NO3)3·4H2O-18C6-CH3COCH3 ternary system at 18℃ have been determined by the scmimicro method. The results indicate that there is only one complex Pr(NO3)3·18C6·4H2Oformed,The different methods have been used to examine the behavior of water in the titled complex. The results indicate the posibility to obtaine a complex species Pr(NO3)3·18C6·2H2O, but our attempts met with the defeat.The stable species of the complex is Pr(NO3)3·18C6The thermal decomposition products and mechanism of this complex have been studied too.
