苯磺酸钕的合成及结构表征

Synthesis and Structural Characterization of Neodymium Benzenesulfonate

以苯磺酸与氧化钕为原料合成苯磺酸钕[Nd(C_(6)H_(5)SO_(3))_(3)·2H_(2)O],通过热重分析、红外光谱、核磁共振光谱、扫描电镜分析对其进行了结构表征,确定了分子结构和表面形貌。苯磺酸钕含2个结晶水,热稳定性良好,表面呈分散的纤维棒状。

Neodymium benzenesulfonate [Nd(C_(6)H_(5)SO_(3))_(3)·2H_(2)O] was synthesized from benzenesulfonic acid and neodymium oxide. Its structure was characterized by thermogravimetric analysis(TG), infrared spectroscopy(IR), nuclear magnetic resonance(NMR) and scanning electron microscopy(SEM). The molecular structure and surface morphology of neodymium benzenesulfonate were determined. The results show that the neodymium benzenesulfonate contains two crystalline water, has good thermal stability, and its surface is in the form of scattered fiber rods.
