摘要
用改进了的半微量相平衡方法研究了Pr(NO_(3))_(3)·4H_(2)O-18C6-CH_(3)COCH_(3)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(No_(3))_(3)·18C6·4H_(2)O。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。
The solubilities of the Pr(NO_(3))_(3)·4H_(2)O-18C6-CH_(3)COCH_(3) ternary system at 18℃ have been determined by the scmimicro method. The results indicate that there is only one complex Pr(NO_(3))_(5)·18C6·4H_(2)O formed,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(NO_(3))_(3)·18C6·2H_(2)O, but our attempts met with the defeat.The stable species of the complex is Pr(NO_(3))_(3)·18C6.The thermal decomposition products and mechanism of this complex have been studied too.
