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
