Abstract:
      A new β-cyclodextrin(β-CD) derivative,2,6-di-O-pentyl-3-O-[(methyl)5 (allyl)2]-β-CD was synthesized.The chromatographic properties of this β-CD derivative were examined and studied by using as a chiral stationary phase in capillary gas chromatography,which showed a good separation ability and a chiral selectivity.Nine kinds of aromatic positional isomers were successfully separated with good resolutions,and parts of their separation results were better than that of 2,6-di-O-pentyl-3-O-allyl-β-CD and other β-CD derivatives.And meanwhile,more than ten kinds of chiral compounds were also determined on this stationary phase.Especially,the separations of some propanoic acid esters with α-substitute were better than those on heterocyclic β-CD derivatives reported in the literature.However,the experimental results showed the chiral separation ability of this stationary phase was still similar to the 2,6-di-O-pentyl-3-O-allyl-β-CD by comparison.It indicated that the introduction of methyl to the part of C3-OH positions may improve the selectivity to aromatic positional isomers,but could not affect obviously the chiral separation ability of the β-CD derivative modified allyl groups on the whole of the C3-OH positions.
