Study of Schiff Base Complexes Derived from Furfural-L-tyrosine and Ln(NO_3) _3·6H_2O

合成了Ln(Ⅲ)(Ln=Gd、Dy、Nd、Er、La、Sm)与糠醛缩 L 酪氨酸席夫碱的6种配合物,通过元素分析、红外光谱、紫外光谱、摩尔电导和热重分析,得到了配合物的组成为[Ln(C14H12NO4)(NO3)(H2O)2](NO3)(H2O)x(x=0～2)。得到了Er配合物的热分解反应动力学机理。

Six complexes derived from furfuralLtyrosine Schiff base and Ln(NO3) 3·6H2O(Ln=Gd,Dy,Nd,Er,La,Sm) are synthesized.Compositions of the complexes are determined by elementary analysis,infrared spectra,ultraviolet spectra,molar conductance and thermogravimetry.The composition can be expressed as (NO3)(H2O)x,(x=0～2).Thermal decomposition reaction kinetics of the Er complex is determined by thermogravimetry.
