摘　　要：用环糊精接枝聚硅氧烷(二环[2,6_二_O_戊基_3_O_己烯基(_5)]五环[2,6_二_O_戊基_3_O_甲基_β_CD聚硅氧烷)作气相色谱固定相成功地拆分具有两个手性中心的物质———2,6_二乙酰氧基庚烷 ;The stereoisomers of 2,6 _ diacetoxyheptane were successfully resolved by capillary gas chromatography using a β _ cyclodextrin bonded polysiloxane, bikis[2,6 _ di _ O _ pentyl _ 3 _ O _ hexenyl( _ 5)] _ pentakis(2,6 _ di _ O _ pentyl _ 3 _ O _ methyl) _ β _ cyclodextrin _ polysiloxane, as a stationary phase. The effect of chromatographic conditions, such as column temperature, on the resolution of the stereoisomers were studied.
