摘要: 采用半微量相平衡方法研究了Y(ClO4)3·3H2O-Bl5C5-CH3CN三元体系在20℃时的溶解度,测定了各饱和溶液的折光率。该体系于20℃生成两种化学计量的配合物,其组成分别为Y(ClO4)3·B15C5·3H2O·2.5CH3CN和Y(ClO4)3·2B15C5·3H2O·CH3CN.用IR光谱、电导、DTG、TG和DSC研究了配合物的组成和性质。

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.
