摘要
本文合成了三种稀土元素异硫氰酸盐与苄胺(C_6H_5CH_2NH_2)的配合物RE(NCS)·4C_6H_5CH_2NH_2(RE=La Pr、Nd)。对其进行了组成分析、元素分析及红外光谱分析。利用TG、DTG热分析手段对三种配合物的热分解进行了研究,利用Coats—Redfern法求出了配合物的第二步热分解过程的动力学参数。
In this paper, We have prepared three complexes of rare earth isothiocya- nates With benzylamine(C_6H_5CH_2NH_2), (RE=La, Ce, Pr). The prepared comp- lexes have been chariterterized by the methods of component analysis and IR SPectra By means of TG and DTG thermal analysis, the thermal decom Position of RE(NCS)_3·4C_6H_5CH_2NH_2 have been studied. Kinetc parameters of the sec- ond step thermal decomposition of the complexes are obtained by Coats--Redfe- rn' s method.
