摘要
我们曾用γ-氯丙基键合硅胶(CPS),在氢化钠(NaH)作用下合成了3-(氮杂-18-冠-6)丙基键合固定相(BCP)[1].该固定相对碱基、核苷酸、硝基苯酚等有较好的分离选择性,但由于NaH对硅胶基质腐蚀作用较大,导致BCP柱效及渗透性较低.本文采...
Aza 18 crown 6)propylsily bonded silica stationary phase for high performance liquid chromatography was prepared via two step solid liquid reaction as follows: porous silica(5 ̄7 μm) was activated using γ chloropropyl triethoxysilane, then reacted with sodium secondary amine salt of monoaza 18 crown 6. The bonded stationary phase shows a good complexing ability with sodium and potassium ions. The chromatographic behavior of disubstituted benzenes and amino acids was investigated on the bonded stationary phase with various mobile phases.
