摘要
制备了一种新的改性β-环糊精,即2,6-二-O-丁基-3-O-乙酰基-β-环糊精手性毛细管气相色谱固定相。采用TGA和DSC热分析法考查了此改性β-环糊精的热行为,静态法制备的玻璃毛细管柱能在190℃稳定工作,其柱效在3000～3500n/m之间,分离了某些氨基酸衍生物,卤代烃和环氧乙烷衍生物对映体。
A novel modified β-cyclodextrin. 2. 6-di-O-butyl-3-O-acetyl-β-cyclodextrin, was prepared and used as a chiral stationary phase in capillary gas chromatography. The TGA and DSC studies of the modified β-cyclodextrin were performed on a PERKIN-ELMER 7 series thermal analysis system. The glass capillary columns with the stationary phase having low melting point and high thermal stability could produce 3000-3500 plates per column meter and have proven to be good chiral columns to resolve the enantiomers of some amino acids, halohydrocarbons and epoxy ethane derivatives, etc..
