Abstract: A new kind of double benzamide crown ether:1S,2S-1-p-(benzamide)phenyl,2-Benzamide-16-crown-5 was synthesized for use as stationary phases in capillary column gas chromatography.Its structure was confirmed by IR,1H NMR,MS and elemental analysis.The chromatographic characteristics,including column efficiency,thermal stability,polarity and selectivity were studied.Excellent selectivity was obtained for the separations of polar position isomers.The benzamide substituent group on crown ether makes the stationary phase have special selectivity for separating anilines and other basic compounds without derivatization.The factors which affect the separation mechanism, including dipole-dipole interactions,hydrogen bonding forces are discussed.

Key words: Gas chromatography, Capillary column, Crown ether stationary phase
