β-环糊精柱分离二氯苯、氯甲苯和二乙烯基苯中位置异构体

Gas Chromatographic Separation of Positional Isomers of Dichlorobenzene, Chlorotoluene and Divinylbenzene on β-Cyclodextrin Column

β-环糊精(简称β-CD)具有独特的空腔结构,可与多种化合物形成稳定性各异的包复物,表现出特殊的选择性分离作用。用β-CD柱已成功地分离了一些苯环多元取代芳香族化合物的位置异构体,但对二氯苯、氯甲苯、乙基乙烯基苯和二乙烯基苯的位置异构体的分离尚未见报道。我们对此进行了分离条件的试验,较好地分离了这些位置异构体。

The GC conditions for the separation of positional isomers of dichlorobenzene, chlorotoluene and diviriyibenzene on β-cyclodextrin column are presented. Various components in raw divinylbenzene were determined at a lower temperature.
