| 摘 要： | 制备了一种新型反相液相色谱固定相──十四烷基胺硅胶键合固定相。以甲醇和水为二元流动相，评价了该固定相的疏水性、选择性和残留硅醇基活性。同时分离了包括碱性、酸性和中性有机化合物在内的混合物。结果表明，在该固定相上，碱性化合物的色谱峰对称性较好，硅酸基活性受到抑制，并具有良好的选择性。

| Abstract: | A novel bonded stationary phase, tetradecylamlne bonded stationary phase(TABP), for reversed-phase HPLC was prepared by bondingl-tetradecylamlne to YWG-80 silica gel through 3-glyci- using aromatic compounds as analytes and methanol-water as binary mobile phase. The organic components and peakshape. The relative retention a for ethylbenzene-toluene was found to be 1.66 and the asymmetry factors of basic aniline, p-toluldlne and N, N- dimethylaniline were found to be 1. 26, 1. 21 and 1.10, respec-tively,with the V(methanol):V(water)=55:45 mobile phase. Aniline was eluted before phenol due to the suppress of the ion exchange activity of residual silanols by the internal masking Interaction. |
