Hg(Ⅱ)与冠醚配位化合物的合成

Syntnesis of Hg(II) and Crown Ether Complex

冠醚化合物具有特殊的配位能力,其研究和应用范围不断扩大,在环境保护和环境医学(如解汞毒药物合成等)等方面的研究已引起重视.冠醚较难配位过渡金属离子,本文讨论除汞的新方法,成功合成了冠醚与氯化汞的配合物,其结构和组成由红外光谱、元素分析等结果所证实,对于进一步弄清冠醚化合物的特性及应用具有一定的意义.

Crown ethers have particular coordination ability. The research and use of them have been deeply extended, and nowdays they receive more attention on their use in environmental protection and medicine.Yet, it is usually difficult for them to coordinate transition metal ions, and this paper try to discuss a new methord to remove mercury, and we successfully synthesized complexes of crown ethers with mercuric choride. Their structures and compositions are verified by IR,EA,etc. It is useful to clarify characters of crown ethers and for the application of them.
