采用半微量相平衡方法研究了三元体系Ｙ（ＣｌＯ４）３·３Ｈ２Ｏ－Ｂ１５Ｃ５—ＣＨ３ＯＨ在２５℃的溶解度，测定了各饱和溶液的折光率．该体系在２５℃生成三种化学计量的配合物，其组成分别为：４Ｙ（ＣｌＯ４）３·３Ｂ１５Ｃ５·１２Ｈ２Ｏ·１２ＣＨ３ＯＨ（Ⅰ）、Ｙ（ＣｌＯ４）３·Ｂ１５Ｃ５·３Ｈ２Ｏ·１．５ＣＨ３ＯＨ（Ⅱ）与Ｙ（ＣｌＯ４）３·２Ｂ１５Ｃ５·３Ｈ２Ｏ·ＣＨ３ＯＨ（Ⅲ），其中配合物（Ⅰ）和（Ⅱ）是溶解不一致化合物．在甲醇溶剂中，分离制备了配合物（Ⅲ），在６９—７２℃下干燥得到配合物Ｙ（ＣｌＯ４）３·２Ｂ１５Ｃ５·３Ｈ２Ｏ．利用ＩＲ光谱、电导测量及Ｘ－射线衍射分析对配合物进行了表征．
The solubility of ternary system Y (ClO4) 3 · 3H2O-B15C5-CH3OH at 25 ℃ was studied by semi-micro phase equilibrium method. The refractive index of each saturated solution was measured. The system produces three stoichiometric complexes at 25 ℃ with the following composition: 4Y (ClO4) 3 · 3B15C5 · 12H2O · 12CH3OH (Ⅰ), Y (ClO4) 3 · B15C5 · 3H2O · 1.5CH3OH And Y (ClO4) 3 · 2B15C5 · 3H2O · CH3OH (III), wherein the complexes (I) and (II) are compounds with dissimilar dissolution. The complex (Ⅲ) is prepared by separation in methanol solvent and dried at 69-72 ℃ to obtain the complex Y (ClO4) 3 · 2B15C5 · 3H2O. The complexes were characterized by IR spectroscopy, conductivity measurement and X-ray diffraction analysis.
