高分子冠醚液晶与全烷基化β－环糊精分离位置异构体的比较

Comparison of Liquid Crystallines Polysiloxane Containing Crown Ether Mesogen and Peralkylated β-Cyclodextrins for the Separation Of Positional Isomers

研究了高分子冠醚液晶（ＰＳＣ－１１）与全甲基β－环糊精、全丙基β－环糊精、全戊基β－环糊精等三种全烷基化β－环糊精分离位置异构体的结果比较，它们在分离分子体积大小不同的化合物时，表现出不同的选择性．

Liquid crystalline polysiloxane containing crown ether mesogen and Peralkylated β-cyclodextrins are highly selective gas chromatographic stationary stationary phases for the separation of positional isomers. The two kinds of stationary phases separate the positional isomers in different modes, so they show different gas chromatographic behaviours.
