摘要
以甘氨酸和异丙醇铝为原料,按摩尔比为1∶1的比例在水相中,75-85℃下反应,得到了产率为97%的水合甘氨酸铝螯合物,并经凯氏定氮法、EDTA滴定法、红外光谱、热重-差热分析、X射线粉末衍射等一系列方法对所得螯合物的结构和组成进行了分析,结果表明该螯合物是带一个结晶水的环状分子化合物,即组成为C2H6A1NO4H2O。
The complex of aluminium glycinate was synthesizwd from glycine and aluminium isopropxide in water medium.The molar ratio of glycine to aluminium isopropoxide was 1∶1,the temperature was between 75~85℃,and the yield was over 97%.After purification,the composition and structure of the complex were characterized by FT IR,XRD and TG-DSC.The chelate was proved to be a compound with one crysta water molecule.The composition is C2H6AlNO4·H2O.
