本文采用蒸发溶剂的方法,合成了较重稀土硝酸盐—硝酸铕与二苯并—18—冠—6的固态配合物。通过元素分析、红外光谱,初步确定了配合物的组成,用显微熔点测定仪观察了配合物在加热过程中的变化,同时测定了不同温度下的红外光谱,并做了差热分析,进而说明了配合物的热稳定性。我们还对配合物进行了电化学性质的研究,进一步确定了配合物的存在。
In this paper, a solid solution of rare earth nitrate-europium nitrate and dibenzo-18-crown-6 was synthesized by evaporation of a solvent. The composition of the complex was preliminarily determined by elemental analysis and infrared spectroscopy. The change of the complex during the heating process was observed with a micro melting point meter. The infrared spectra at different temperatures were also measured and the differential thermal analysis The thermal stability of the complex is illustrated. We also studied the electrochemical properties of the complexes to further confirm the existence of the complexes.
