Abstract: A new kind of thio crown ether stationary pases, ω-undecylene thio-15-crown-5,was synthesized.This stationary phase indicates good thermal stability, medium polarity and excellent selectivity for n-alcohols, ester and aromatic compounds,their chromatographic characterization and separation mechanism have been investigated by measuring various thermodynamic parameters.The separations of di-chloro benzene, nitro toluene and di-nitro toluene position isomers on the column were made as examples.

Key words: Crown ether polysiloxane, Stationary phase, Gas chromatography
