摘要
合成了一种新型聚硅氧烷侧链全氧冠醚（丙烷氧基１５－冠－５）。用其涂渍的弹性石英管柱柱效较高，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。
A new kind of crown ether,propyloxymethyl-15-crown-5 sidechain polysiloxane was synthesized and coated on capillary columns.Its chromatographic characteristics including column efficiency,operating temperature range,thermal stability, polarity and selectivity were studied,and its separation mechanism was discussed.
