摘要: 本文合成了2种新型聚硅氧烷侧链全氧冠醚(十一烷氧甲基18-冠-6和十一烷氧甲基15-冠-5),并将其涂渍、交联在未经处理的弹性石英毛细管柱上,其柱效较高,使用温度范围较宽,热稳定性和选择性较好.研究了固定液对样品的分离机理.

关键词: 固定相, 冠醚, 聚硅氧烷, 石英毛细管柱, 气相色谱

Abstract: Two new kinds of crown ether, n-undecyloxymethyl-18-crown-6(or 15-crown-5) side-chain polysiloxane were prepared and coated on capillary column. Their chromatographic characteristics including column efficiency, allowable operating temperature range, thermal stability, polarity and selectivity were studied, and their separation mechanism was discussed.
