氯化稀土与丙氨酸配合物热分解过程研究

Study on Thermal Decomposition Mechanism of Complexes of Rare Earth(Ⅲ)Chlorides with α-alanine

采用ＴＧ－ＤＴＧ法，在氮气气氛下对氯化稀土与丙氨酸的２４种配合物的热分解机理进行研究。发现稀土盐与丙氨酸形成摩尔比不同，其分解机理不同；而相同摩尔比的配合物的分解机理与阳离子有关。

Thermal decomposition mechanism of 24 kinds of complex of rare erath(Ⅲ)chlorides withα-alanine are investigated in dynamic atmosphere of dry nitrogen by means of TG-DTG technique.The results show that there are different thermal decomposition mechanisms for different types ofcomplex , while thermal decomposition mechanism of same type of complex is related to rare earth(Ⅲ) ions.
