合成了稀土高氯酸盐与咪唑、DL-a-丙氨酸的两种配合物晶体.经傅立叶变换红外光谱(FT-IR)、元素分析和化学分析测定后确定其组成为[Ln(C3H7NO2)2(C3H4N2)(H2O)](ClO4)3(Ln=Eu,Dy).用差示扫描量热法(DSC)在高纯流动N2气氛下测定了两种配合物的热分解数据,它们的热分解过程都是由两个放热峰组成,两个配合物开始分解的温度分别为497.2K,491.8K,峰顶温度分别为564.4K和613.2K,544.4K和615.1K,热分解焓值分别为2026kJ/mol和961.2kJ/mol,2596kJ/mol和1097kJ/mol.测定结果表明配合物有较高的热稳定性.
The complexes of rare earth perchlorate with imidazole and DL-a-alanine were synthesized and characterized by Fourier transform infrared spectroscopy (FT-IR), elemental analysis and chemical analysis, and their compositions were determined to be [Ln (C3H7NO2 ) 2 (C3H4N2) (H2O)] (ClO4) 3 (Ln = Eu, Dy) The thermal decomposition data of the two complexes were measured by differential scanning calorimetry (DSC) Thermal decomposition process is composed of two exothermic peaks, two complexes began to decompose at temperatures of 497.2K, 491.8K, the peak top temperature was 564.4K and 613.2K, 544.4K and 615.1K, the thermal decomposition enthalpy The values were 2026 kJ / mol and 961.2 kJ / mol, 2596 kJ / mol and 1097 kJ / mol, respectively. The results showed that the complex has high thermal stability.
