摘要
将合成的席夫 (Schiff)碱侧链聚硅氧烷高分子液晶化合物用作毛细管柱气相色谱固定相 ,具有较高的柱效 ,热稳定性较好 ,最高柱温可达 2 80℃ ;对苯的各种取代物、酚类及多环芳烃有良好的选择性 ,尤其对位置异构体有独特的分离效果。
A new stationary phase, Shiff-base side-chain polysiloxane was synthesised and used in capillary column gas chromatography. It shows higher efficiency, with 2560 plates/m for anthracene at 180degreesC, has better thermostability and can be used under the temperature of 280degreesC. It exhibits excellent selectivity to some organic compounds such as replaced-benzenes, phenols and polycyclic aromatic hydrocarbon, especially positional isomers. The mixture of anthracene, phenanthrene, fluorene and acenaphthylene, dimethyl phenols and dichlorobenzene are separated well.
