Abstract: The present paper covers a new method for the preparation of glass capillary columns with dicarboxyl crown ether stationary phase and their chromatographic characteristics, including column efficiency, phase transition temperature, thermal stability, polarity and selectivity.It is shown that they have good chromatographic characteristics and unique selectivity in the separation of some polar position isomers.The reaction mechanism and the factors which affect the separated mechanism are discussed.
