以三嵌段聚醚P123为模板,四乙氧基硅烷为前驱体,在强酸性条件下合成了高比表面积、大孔径、微米级的球形SBA-15.将纤维素-三(3,5-二甲基苯基氨基甲酸酯)(CDMPC)涂敷在氨丙基化的SBA-15微球上,作为手性固定相,在正相条件下直接拆分了七种不同类型的手性化合物.实验发现,与同样尺寸的CDMPC涂敷的氨丙基硅胶手性柱相比,手性化合物在所制备的新型手性固定相上有较强的保留、具有较高的分离因子;新制备的手性固定相不仅有较好的渗透性,而且具有较高的手性识别能力.因此,高比表面的介孔SBA-15微球适合作为手性色谱填料基质.“,”Cellulose-tris(3,5-dimethylphenylcarbamates) (CDMPC) coated on mesoporous silica SBA-15 (SBA@CDMPC) with a high surface area and large pore diameters was applied in chiral high performance liquid chromatography (HPLC). The direct enantioseparation of seven chiral compounds has been achieved using n-hexane/alcohol as the mobile phase. Chromatographic behavior of chiral compounds on SBA@CDMPC was compared with that on CDMPC coated on silica gel (SG@CDMPC) by hex- ane-isopropanol as the mobile phase. The result suggests that SBA@CDMPC shows high chiral recognition abilities in chiral HPLC. SBA@CDMPC is a suitable chiral stationary phase (CSP) for the optical resolution of a lot of racemates by HPLC.
