摘要: 安替比林(AP)及其4位衍生物是金属离子的良好配位试剂,它可以与许多稀土盐配位形 成组成不同的配合物.可以用于稀土盐的分析、分离和提纯[1];还可以用于发光材料[2,3].对桥连双安替比林类衍生物的研究较少,仅限于二安替比林甲烷及其同系物[4]和N,N-二安替比林硫脲[5].为进一步研究安替比林衍生物与稀土盐配位所形成的配合物的性能,合成了具有桥链结构的多齿配位体N,N-二安替比林-1,6-己二酰胺(BAPHDCA)[6],本文用溶解度等温 法[7]研究三元体系Sm(ClO4)3-BAPHDCA-H2O的相平衡,确定了全浓度范围内BAPHDCA与稀土盐的作用行为以及三元化合物Sm(BAPHDCA)2(ClO4)3·4H2O的特殊制备条件.

Abstract: In the study of the solubility properties of the system of Sm(ClO4)3 BAPHDCA H2O at 30 ℃ in the whole concentration range by phase equilibrium method a ternary compound Sm(BAPHDCA)2(ClO4)3·H2O has been found. According to the phase equilibrium results the complex was prepared and characterized by chemical and elemenal analysis, IR spectrometry and TG DTG techniques.
