本文报道了硝酸铀酰、氯化铀酰和硝酸钍与冠醚DB18CR6、B15CR5、18CR6通过溶剂反应制得的8个固体络合物,对这些络合物进行了熔点测定、元素成分测定和红外光谱分析。其中4个络合物的化学组成与文献报道不同,它们的化学式为:UO_2(NO_3)_2·2H_2O·[DB18CR6]_2;[Th(NO_3)_4]_3·[DB18CR6]_5·3H_2O;[Th(NO_3)_4]_2·[B15CR5]_3·2H_2O;[Th(NO_3)_4]_2·[18CR6]_3·2H_2O。
In this paper, eight solid complexes of uranyl nitrate, uranyl chloride and thorium nitrate with crown ethers DB18CR6, B15CR5 and 18CR6 were prepared via solvent reaction. Their melting points, elemental compositions and infrared Spectral analysis. The chemical compositions of the four complexes are different from those reported in the literature. Their chemical formulas are as follows: UO 2 (NO 3) 2 · 2H 2 O · [DB18CR6] 2; [Th (NO 3) 4] 3 · [DB18CR 6] 5 · 3H 2 O; (NO_3) _4] _2 · [B15CR5] _3 · 2H_2O; [Th (NO_3) _4] _2 · [18CR6] _3 · 2H_2O.
