摘要
合成了三种稀土酪氨酸配合物。通过化学分析,元素分析,红外光谱,x射线衍射,热分析等,确定了所得配合物的组成,其通式为Ln(Tyr)mCl_3·nH_2o(Ln=Pr,m=1.5,n=4;Ln=Dy,·m=2,n=5;Ln=Y,m=2,n=6;Tyr=Tyrosine)。研究了它们的分解机理,求得了它们各分解阶段的表观活化能和脱水焓。
In this paper,three solid coordination compounds of rare earths with tyrosine have
been prepared in anhydrous alcohol media.Their formula is Ln(Tyr)_mCl_3·nH_2O
(Ln=Pr,m=1.5,n=4;Ln=Dy,m=2,n=5;Ln=Y,(?)=2.n=6;
Tyr=Tyrosine)The compositions and structures of these new compo(?)nds have been de-
termined by the methods of chemical analysis,elemental analysis,IR,X-ray powder
diffraction and thermoanalysis.Some physical and chemical properties have also been
invesigated.
