摘要: 合成了一种苄基取代的环糊精衍生物2,6-二-O-戊基-3-O-苄基-β-CD,研究了其气相色谱分离性能,发现此固定相涂渍性好,极性适中,是一种良好的气相色谱固定相,对甲酚、二甲苯等难分离的二取代苯的位置异构体具有良好的分离能力.2,6-二-O-戊基-3-O-苄基-β-CD因其特有的空腔结构,具有比OV-225更好的分离性能.

Abstract: A β-cyclodextrin derivative, heptakis(2,6-di-O-pentyl-3-O-benzyl)-β-CD, was synthesized and used as GCstationary phase. The chromatographic results show that the CDs is a good GCstationary phase with a good film forming property, moderate polarity and good separation ability to disubstituted benzene isomers such as cresols and xylene isomers. The chromatographic properties of heptakis(2,6-di-O-pentyl-3-O-benzyl)-β-CDare better than OV-225 because of the peculiar cavity of β-cyclodextrin.

Key words: Capillary gas chromatography, Stationary phase, Cyclodextrin derivatives
