| 摘 要： | 合成了一种新型的杯4]芳烃高效液相色谱键合固定相，考察了它的反相色谱行为．通过对多环芳烃、二取代苯的位置异构体、苯甲酸酯和邻苯二甲酸酯的分离，发现该键合相具有显著的反相特征，对位置异构体具有很高的识别能力，其分离明显优于C18柱，并讨论了可能的分离机理．

| Abstract: | For the first time calix4]arene tetraamide bonded stationary phase was prepared by modifying silica gel with 3 mercaptopropyltriethoxysilane and coupling with p allylcalix4]arene tetraamide. The separation of polycyclic aromatic hydrocarbons, positional isomers of nitroaniline, benzoic esters and phthalic esters on the new calix4]arene bonded stationary phase was achieved with acetonitrile water or methanol water as mobile phase. A comparison with conventional reversed phase C 18 columns shows a predominant reversed phase character and obvious priority for separation of positional isomers. The possible separation mechanism has been investigated. |
