摘要
为了探索稀土盐与冠醚在有机溶剂中的配合行为,利用半微量相平衡法对Sm(NO_2)_3·3H_2O-Bl5C5-CH_3COCH_3三元系的溶度(291K)进行了研究,结果发现仅有一种配合物Sm(NO_3)·Bl5C5·3H_2O·CH_3COCH_3生成。进而制备了固体配合物。利用化学分析,紫外光度分析,红外光谱和热分析研究了它的组成和性质,测得了热分解历程及相应的焓变值。
The solubilities of the ternary system Sm( NO_3)_ 3·3H_2O -BI5C5 -CH_3COCH_3(29IK) have been investigated by the modified semimicro phase. equilibrium method. The results found that only one was fonmed complex Sm ( NO_2) _3 ·BI5C5· 3H_2O·CH_3COCH_3. The solid complex were prepared, The composition and properties of this complex have been examined by chemical analysis, UV-spectra, IR-spectra, and thermal analysis. We have studied the decomposition process and determined the changes in enthalpy of these process.
