双活性官能团冠醚固定相的合成及毛细管柱的研制

本项研究合成了一种新的气相色谱固定相：３－端烯丙基－不对称二苯并１４－冠－４－二羟基冠醚。其结构经元素分析、红外光谱、核磁共振及质谱的数据证实。将这种固定相涂渍在弹性石英毛细管内，测定其柱效、热稳定性、平均极性及选择性。结果表明：该固定相具有良好的色谱特性，对某些极性位置异构体有着良好的选择性。

Synthesis and Preparation of Double Active Functional Group Crown Ether Stationary Phase for Capillary Gas Chromatography(GC)

n this paper a new stationary phase for GC,3-allvl-unsymmetry dibenzo- l4-crown-4-dihydroxycrownether , was synthesized and coated on a fused silica capillary column. The structure was confirmed byelemental analvsis,IR,1HNMR and MS.Chromatographic characteristics including column efficiency,thermal stability,polarity and selectivitywere studied.It was shown that they have good chromatographic characteristics and unique selectivity in theseparation of some polar positional isomers.
