摘要
本文合成了15种稀土马尿酸配合物,用元素分析、红外光谱,紫外光谱,差热热重等方法研究了马尿酸配体和稀土的配位情况以及配合物的性质递交规律,并用气相色谱程序升温法研究了配合物的热分解机理.
15 rare earth hippurate have been synthesized and characterized by IR spectra, UV reflectance speactra, TG and DTA. The results are that the plot of maximun absorption peaks λmax in UV reflectance spectra against atomic number Z reveals tetrad effect, the plot of the temperature of en-
dothermic peak and exothermic peak against atomic number also shows, te-
trad effect. In addition thermal decomposition mechanism was proposed.
