本文用溶剂蒸发法培养了18—冠—6与CdCl_2配合物的单晶,对其进行了熔点测定,元素分析、红外光谱分析和热分析,并做了X射线单晶衍射实验,对所分析的结果给以表征。 1967年美国化学家C.J.Pederson首次合成了冠醚。由于这类中性的有机化合物具有环状的空腔结构而具有许多独特的配位性能。其在有机合成化学、金属离子的萃取分离、分析化学及生物学等领域的广泛应用引起世界各国学者极大的研究兴趣,并且法国科学家使用冠醚从海水中富集铀取得了成功。本文用蒸发法培养了18—冠—6与CdCl_2配合物的单晶,就目前文献查阅,尚未见报道。
In this paper, the single crystal of 18-crown-6 and CdCl_2 was grown by solvent evaporation. The melting point, elemental analysis, infrared spectrum and thermal analysis of the single crystal were studied. The X-ray single crystal diffraction experiment was done. The results are given for characterization. 1967 American chemist C.J.Pederson first synthesized crown ether. This type of neutral organic compound has many unique coordination properties because of its ring-like cavity structure. Its extensive applications in organic synthesis chemistry, extraction and separation of metal ions, analytical chemistry and biology have attracted great interest of scholars all over the world and the success of French scientists enriching uranium from seawater by using crown ether. In this paper, the single crystal of 18-crown-6 and CdCl 2 complexes was cultured by evaporation method. However, it has not been reported in the current literatures.
