摘要: 由2,6-二羟甲基-4-甲基(或磺酸基)苯酚分别和芳香族冠醚(B15C5、B18C6、DB18C6、DB24c8等)在强酸催化剂下缩聚,合成了2个系列冠醚共缩聚物。它们的萃取能力和配合作用均优于相应的单冠醚,并可作为树脂吸附分离多种金属离子,作为配合剂测定钾、钠以及作为气相色谱固定液分离多种有机物。

关键词: 冠醚, 苯酚化合物, 共缩聚物, 阳离子分离

Abstract: Nine phenolic polycondensates with crown ethers were prepared by the condensation of 2,6-dihydroxymehtyl-4-methyl phenol (or 2,6-dihydroxymethyl-4-sulfo phenol) with d1benzo-18-crown-6(2B18C6),dibenzo-24-crown-8 (2B24C8),benzo-15-crown-5 (B15C5), benzo-18-crown-6(B18C6)respectively, and characterized by IR, 1H NMR and DSC. The polymeric crown ethers can be used as complexing resins to enrich cations and as stationary phase in gas chromatography for separation of mixed organic compounds.

Key words: crown ether, phenol derivative, copolycondensate, cation isolation
