摘要
合成了一种新的环糊精接枝聚硅氧烷固定相(DPP_β_CD),并将其成功涂渍到气相色谱毛细管柱上,发现其涂渍性能良好。对二甲苯、氯苯胺等难分离的芳香族位置异构体和一些对映异构体具有好的分离能力,是一种有应用前景的气相色谱固定相。
A newβ_cyclodextrin derivative bonded polysiloxane(DPP_β_CD)was synthesized,and coated on capillary columns as a stationary phase for gas chromatography.Its chromatographic performance is good with satisfactory capability of coating formation and isomer separation.It is a promising stationary phase for the separation of aromatic positional and chiral isomers of xylene,chloroaniline,and enantiomers as well.
