摘要
采用半微量相平衡方法研究了Y(ClO_4)_3·3H_2O-18C6-CH_3COCH_3/C_2H_5OH/CH_3OH三元体系在25℃的溶解度,测定了各饱和溶液的折光率。考察了在相平衡过程中水的行为。在3个体系中共发现了8种新配合物。系统地比较了在不同有机溶剂中的配合行为。在相平衡结果的指导下,合成制备了固态配合物,利用化学分析,IR,TG,DTG与DSc研究了固态配合物的组成和性质。
The solubilities of the ternary systems, Y(ClO_4)_3·3H_2O-18C6-CH_3COCH_3/C_2H_5OH/CH_3OH,at 25℃ have been investigated by the modified semimicro methed for study of equilibrium; the refraction indexes of the saturated solutions in these systems have been measured; the behavior of water in these systems during equilibrium has been determined. Eight coordination compounds have been found in these systems. Under the direction of the phase equilibrium results, the solid coordination compounds have been synthesized and their compositions and properties have been investigated by chemical analyses, IR, TG, DTG and DSC. Coordination behaviors in different organic solvents have been compared systematically.
