近年来,稀土冠醚配合物的研究受到重视,但稀土高氯酸盐冠醚配合物的研究报道尚少,有关高氯酸钇与18-冠-6(18C6)的配合物还未见报道。我们用改进的半微量相平衡方法研究了Y(ClO_4)_3·3H_2O-18C6-CH_3CN三元体系在20℃时的溶解度,以便确定三水高氯酸钇与18-冠-6在乙腈中能否形成配合物,能生成几种配合物,以及它们的相区如何,为合成固态配合物提供依据。在此基础上,分离、制备了固态配合物,利用化学分析,DTG、TG、DSC以及电导考查了配合物的组成与性质。
In recent years, the research of rare earth crown ether complexes has received great attention, but few studies on the complexes of rare earth perchlorate with crown ether have been reported. The complexes of yttrium perchlorate with 18-crown-6 (18C6) have not been reported . The solubility of Y (ClO_4) _3 · 3H_2O-18C6-CH_3CN ternary system at 20 ℃ was studied by a modified semi-micro phase-equilibria method in order to determine the solubility of yttrium perchlorate perchlorate and 18-crown-6 in acetonitrile No formation of complexes, can generate several complexes, as well as their phase region, provide the basis for the synthesis of solid complexes. On this basis, the solid complexes were isolated and prepared. The composition and properties of the complexes were investigated by chemical analysis, DTG, TG, DSC and conductance.
