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.
