在30℃时采用等温溶度法研究了三元体系La(ClO4)3-BAPHDCA-H2O(BAPHDCA, N, N'-二安替比林-1, 6-己二酰胺)的相平衡, 绘制了体系的溶度图及饱和溶液的折光指数-组成图,发现并制备了未见文献报道的固液异组成三元化合物La(BAPHDCA)2(ClO4)3.4H2O。通过化学分析、元素分析、IR光谱、TG-DTG及X射线粉末衍射分析等对其进行了物理化学表征。

Solubility and refractive indexes of the saturated solutions of the titled system at 30℃ have been studied and the corresponding equilibrium diagram and refractive index diagram were constructed. Both solubility curves and refractive index curves of the system consist of three branches, corresponding to BAPHDCA, La(BAPHDCA)2(ClO4)3.4H2O and La(ClO4)3.8H2O respectively. La(BAPHDCA)2(ClO4)3.4H2O is a new compound. It was characterized by IR spectra, TG-DTG, X-ray powder diffraction, as well as chemical and elemental analyses.
