Abstract
Using the cyclodextrin bonded polysiloxane (bikis〔（2,6-di-O-pentyl-3-O-hex-6-O-enyl)-pentakis(2,6-di-O-pentyl-3-O-methyl)-β-cyclodextrm-polysiloxane〕) as gas chromatographic stationary phase, α-hydroxy acetones were separated and the values of the enantiomeric excess(e.e) of 3-hydroxy-2-butanone were determined. The results showed that the high resolution gas chromatography (HRGC) using the chiral gas chromatographic stationary phase could determine the productive rate of the asymmetric hydrogenaton reaction and evaluate the enantoselectivity of the catalyst system.
