β cyclodextrin/silica gel bonded stationary phases containing different content of β cyclodextrin were prepared The characterizations of bonded phases were determined with IR spectrometry
elemental analysis and thermal analysis The TLC plates with the solvent systems of petroleum ether/ethyl acetate/methanol and petroleum ether/ethyl cetate/acetonitrile were used for the separation of six pairs binaphthol enantiomers Significant chromatographic selectivity was obtained with relative R f values between 1 19 to 1 68 Effects of different reaction conditions on β cyclodextrin contents in bonded stationary phases were studied
