摘要: 本文研究了含有羰基的冠醚与铀、钍硝酸盐的络合作用,合成了组成为1:1(金属离子/冠醚)的固态络合物Th(NO_3)_4·C_(11)H_(18)O_7·H_2O和组成为2:3的固态络合物UO_2(NO_3)_2_2·C_(11)H_(18)O_7_3·H_2O,测定了熔点,并对这些络合物进行了元素分析、X射线衍射物相分析、红外光谱及差热热重分析。

Abstract: Complexes of the macrocyclic polyether 2,4-diketo-16-crown-5 with Th(NO3)4·6H2O and UO2 (NO3)2·6H2O are prepared in solid state and characterized by chemical analysis, infrared spectra, as well as thermogravimetric (TG) and differential thermal analyses (DTA). X-ray powder diagrams of these compounds indicate that real complexes are formed.The complexes obtained are proved to be Th(NO3)4·C11H18O7·H2O and UO2(NO3)22· C11H18O73·H2O.
