摘要: 双冠醚化合物对某些金属离子比单冠醚具有更好的络合性能和选择性,它们合成、应用研究越来越受到人们的重视,本工作采用2,6-二羟甲基对甲氧基苯酚为缩合剂与芳香族冠醚缩聚,得到一系列具有双冠醚结构特征的新酚醛型聚苯并冠醚(简称聚冠醚),聚冠醚合成容易,并呈现了比相应单冠醚更优越的络合萃取能力和富集效率。

关键词: 缩聚, 聚冠醚, 络合萃取, 富集效率

Abstract: Five new polycondensates of phenolic and crown ethers are prepared by the condensation of 2,6-dihydroxymethyl-4-methoxylphenol with dibenzo-18-crown-6(2B18C6), dibenzo-24-crown-8(2B24C8), dibenzo-30-crown-10 (2B30C10), benzo-15-crown-5 (B15C5), benzo-18-crown-6(B18C6), respectively. The collecting efficiency of polymeric crown ether (PB15C5) for K+, Ag+, Mg2+, Pb2+, Cu2+(10-6-10-4mmol/mL) come close to 100%.

Key words: Condensation, Polymeric crown ether, Complexing extraction, Collecting efficiency
