稀土金属樟脑磺酸盐的制备和表征

Preparation and Characterization of Rare Metal Camphorsulfonates

合成了3种稀土金属(镧、钕和铈)樟脑磺酸盐,并用红外光谱(FTIR)和热重(TGA)分析进行了表征。TGA研究表明,所合成的3种盐分别含有7.72、6.26和5.93个结晶水。研究了其无水化合物的热稳定性,结果表明,樟脑磺酸铈的热稳定性较弱,樟脑磺酸镧和樟脑磺酸钕的热稳定性较强。并分析了空气气氛下各种盐的最终分解产物。

Three kinds of rare metal （La, Nd and Ce） camphorsulfonates were synthesized. The composition and properties of these complexes were characterized by Fourier transform infrared spectroscopy（FTIR） and Thermogravimetric analysis （TGA）. As shown in TGA, the salts prepared contained 7.72, 6.26 and 5.93 water molecules, respectively. And the thermal stability of anhydrous compounds were discussed. The thermal stability of Ce（C10H15O4S）3 was lower. The thermal stabilities of La（C10H15O4S）3 and Nd（C10H15O4S）3 were higher. The final thermal decomposition products were studied in dynamic air atmosphere.
