L-α亮氨酸稀土硝酸盐固体配合物的研究

Study on Solid Compounds of L-α-Leucine with Rare Earth Nitrates

本文在苯和无水乙醇混合溶剂中,制得了稀土硝酸盐和L-α-亮氨酸的4种1:3型固体配合物。经化学分析、元素分析、IR和X-粉晶衍射分析确定了配合物的组成,确定其通式为RE(Leu)_3(NO_3)_3·nH_2O(RF=Ce.Nd.Sm.Eu;Leu=Leucine)。还测定了它们的熔点及在水中的电导过TG-DTG讨论了配合物的热分解过程。

This paper introduces four 1:3 coordination compounds of rare earth nitrates with L-α-Leucine prepared from benzene-ethyl-alcohol(absolute) mixed solvent. The composition and structure of the compounds have been determined by chemical analysis. IR spectra and X-ray powder diffraction. The general formula of these complounds is RE(Leu)_3(NO_3)_3·nH_2O (RE=Ce. Nd. Sm. Eu; Leu=leucine). Electric conductivity in aqueous and their melting points have also been determined. The thermal decomposition process of RE(Leu)_3(NO_3)_3·nH_2O was studied based on TG-DTG.
