摘要
在无水乙醇和苯的混合溶剂中,制得了稀土硝酸盐和L—a亮氨酸的6种固体配合物.经化学分析、元素分析和热重分析确定了其组成是RE(Leu)_3(NO_3)_3H_2O(RE=Pr,Nd,Sm,Eu,Gd)和Dy(Leu)_4(NO_3)_3·H_2O(Leu=Leucine亮氨酸);测定了熔点,并通过TG—DTG比较了它们的热稳定性.
The six coordination compounds of rare earth nitrates with L—a—Leucine prepared from benzene—ethyl—alcohol (absolute) mixed solvent are obtained. The composition and structure of compounds have been determined by chemical analysis, element analysis and thermogravimetris analysis, The general formula of these compounds is RE (Leu)_3 (NO_3)_3·H_2O (RE=Pr、Nd、Sm、Eu、Gd)and Dy (Leu)_4(NO_3)_3·H_2O(Leu=Leucine)Their melting points have also been determined. It is foumd that the thermal stability of liquid is higher than the complexes, and their thermolysis are put forword.
