摘要:

摘 要： 以C60和精氨酸为原料经亲核加成反应合成得到C60精氨酸，C60精氨酸再与硝酸铅反应得一种C60金属盐衍生物—C60精氨酸铅盐。同时采用FT-IR、MS、UV-Vis、AAS、XRD、XPS以及等测试手段对产物结构进行了表征。采用热重分析法对其失重情况进行了研究，失重率为57.86%，采用差热分析法对C60精氨酸铅盐的热稳定性进行了研究，结果表明，在空气气氛下，DSC分解峰值温度为285℃、435℃；目标产物表现出良好的热稳定性。

Abstract:

Abstract: The C60 arginine was prepared with C60 and arginine as the raw material. The C60 arginine lead salt was synthesized by the reaction of C60 arginine with lead nitrate, and characterized by FT-IR, MS, UV-Vis, AAS, XRD, XPS and Elemental analysis as a new combustion catalyst. The thermal stability of C60 arginine lead salt was also carried out by DSC and TG-DTG under air atmosphere, and two discrete regions of thermal decomposition can be observed in the DSC curve at 285℃ and 435℃ respectively. C60 arginine lead salt has two-steps weight loss, overall weight-loss was 57.68% in the TG-DTG curve, which shows good thermal stability.
