| Abstract: | Two new kinds of crown ether, n-undecyloxymethyl-18-crown-6(or 15-crown-5) side-chain polysiloxane were prepared and coated on capillary column. Their chromatographic characteristics including column efficiency, allowable operating temperature range, thermal stability, polarity and selectivity were studied, and their separation mechanism was discussed. |
