【摘要】 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．更多还原

【Abstract】 The solubilities of the ternary system,Y(ClO4)3.3H2O-B15C5-CH3OH,at 25℃ havebeen investigated by the semimicro method of phase equilibrium study.The refractive indexes ofsaturated solutions have been determined. There are three coordination compounds formed inthe system at 25℃. The compositions of the three coordination compounds arc:4Y(ClO4)3.3B15C5.12H2O. 12CH3OH(Ⅰ),Y(ClO4)3. B15C5.3H2O.1.5CH3OH(Ⅱ)and Y(ClO4)3.ZB15C5.3H2O. CH3OH(Ⅲ).The coordination compounds (Ⅰ) and (Ⅱ) are solubleincongrucntly.The coordination compound(Ⅲ) has been isolated from methyl alcohol solutionand dried between 69-72℃ to give Y(ClO4)3. 2B15C5 - 3H2O.The properties of Y(ClO4)3.2B15C5.3H2O has been characterized by IR, conductivity measurement and X-ray diffractionanalysis.更多还原
