摘要
冠醚键合固定相主要用于一些无机离子的分离，我们用连续固液相法合成了一系列冠醚键合硅胶固定相，并成功地用于有机化合物的分离［１～４］；β－ＣＤ的内腔疏水而外缘亲水，可以选择性地包结含苯环及萘环的化合物，且具有手性拆分能力，已被用于手性色谱固定相［５，...
A mixed functional stationary phase containing aza crown ether and cyclodextrin for highperformance liquid chromatography was prepared via a continuous solidliquid reaction method. The new mixed functional stationary phase was used to separate some disubstituted benzene isomers such as nitrophenols, nitroanilines and phthalic acids. The results show that the separation ability of the new mixed functional stationary phase for the disubstituted benzene isomers is better than that on the aza crown ether bonded silica and cyclodextrin bonded silica stationary phases. Chiral separations of glycine derivatives, PMGly, MPGly and BPGly, were partially achieved on the new mixed functional stationary phase with phosphate buffer solution as the mobile phase.
