摘要
合成了两种不同构象的杯芳烃衍生聚合物(杯芳冠醚聚硅氧烷c-c[4]c5-pso和二乙氧基杯[4]芳烃聚硅氧烷p-c[4]-pso),并将其用作毛细管气相色谱固定液,使用温度高达320℃,对不同的极性化合物,特别是对酚类异构体有很好的分离能力.同时也研究了分离机理.
Two new kinds of calix [4]arene polysiloxane, cone bis (undecenyloxy)-p-tert-butyl calix [4]crown-5 polysiloxane (c-c [4]c5-pso) and partial cone 5, 11, 17, 23-tetra-tert-butyl-25, 27-diethoxy-26, 28-diundecenyl calix[4] arene polysiloxane(p-c[4]-pso), were syn-thesized and used as the stationary phases for capillary gas chromatography for the first time.They exhibit a good thermal stability and an excellent selectivity for alcohols,benzene series,halohydrocarbon,aromatic compounds,especially for substituted phenol isomers.The separation mechanism has also been investigated.
