Abstract: The solubilities of ternary system,Y(ClO4)3·3H2O-Bl5C5-CH3CN,have been investigated by a semimicro method at 20℃ for study of phase equilibrium,and the refractive indexes of saturated solutions have been determined.The results indicate that there are two kinds of complexes formed in the system , namely,Y(ClO4)3·Bl5C5·3H2O·2.5CH3CN and Y(ClO4)3·2Bl5C5·3H2O·CH3CN.Their compositions have been determined and properties have been characterized by IRspectra,conductivity measurements,DTG,TG and DSC.
