Respectively, glutamic acid derivatized β-CD has been synthesized with epoxy chloropropane as the intermediate, a water-insoluble yellow liquid was got after the acetylating of the by using acetic anhydride, which was used as a novel gas chromatographic CSP; A water-soluble β-CD polymer cross-linked with epoxy chloropropane has been synthesized, and the derivatives of β-CD polymer were synthesized by its alkylating and acetylating. The different β-CD derivatives were coated on silica capillary columns by dynamic method, the chromatographic properties and retention behaviors of the fused silica capillary columns were studied, the results showed that the β-CD derivatives had good stereoselectivity and separation results to some compounds, especially to various positional isomers and enantiomers.
