| 摘 要： | 本文用改进和半微量相平衡方法研究了Y(ClO~4)~3.3H~2O-18C~6-CH~3Cn 三体系在20℃时的溶解度, 以便确定三水高氯酸钇与18-冠-6-在乙腈中能否形成配合物, 能生成几种配合物以及它们的相区情况, 为合成固态配合物提供依据。并在该基础上, 分离,制备了固态配合物, 利用化学分析, DTG,TG,DSC以及电导考查了配合物的组成与性质。

| Abstract: | The solubilities of the ternary Y(ClO4)3.3H2O-18-crown-6-MeCN system at 20?have been investigated by the modified semimicro method for study of phase equilibrium Two kinds of complexes are formed at 20? namely Y(ClO4)3.18-crown-6.3H2O.2.5MeCN and Y(ClO4)3.2(18-crown-6).3H2O.2MeCN, which were isolated, and dried to give Y(ClO4)8.18-crown-6.3H2O and Y(ClO4)3.2(18-crown-6).3H2O, resp. The composition and properties of the 2 complexes have been investigated by IR spectra, conductivity measurements, DTG, TG and DSC. The enthalpies of dehydration and decompns. have been determine for these two complexes by DSC. |
