摘要
采用半微量相平衡方法研究了Ｙ（ＣｌＯ_４）_３·３Ｈ_２Ｏ－Ｂｌ５Ｃ５－ＣＨ_３ＣＮ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（ＣｌＯ_４）_３·Ｂ１５Ｃ５·３Ｈ_２Ｏ·２．５ＣＨ_３ＣＮ和Ｙ（ＣｌＯ_４）_３·２Ｂ１５Ｃ５·３Ｈ_２Ｏ·ＣＨ_３ＣＮ。用ＩＲ光谱、电导、ＤＴＧ、ＴＧ和ＤＳＣ研究了配合物的组成和性质。
The solubilities of ternary system,Y(ClO4)3·3H2O-Bl5C5-CH_3CN,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 IR spectra,conductivity measurements,DTG,TG and DSC.
