淀粉及纤维素三(3-三氟甲基苯基氨基甲酸酯)手性固定相的制备及其性能评价
Preparation and evaluation of amylose and cellulose tris(3-trifluoromethylphenylcarbamates)-based chiral stationary phases
摘要
Abstract
To broaden the category of polysaccharide-based chiral stationary phases ( CSPs ), coated CSPs based on tris( 3-trifluoromethylphenylcarbamates ) of amylose and cellulose were prepared for enantioseparation in high performance liquid chromatography. Their performances were evaluated by eight racemates using hexane-isopropanol as mobile phase. Compared with the most widely used, commercially available polysaccharide-based CSPs, Chiralpak AD and Chiralcel OD, utilizing tris( 3,5-dimethylphenylcarbamates ) of amylose and cellulose as the chiral selector, respectively, the obtained CSPs exhibited lower enantioseparation abilities. However, cellulose tris( 3-trifluoromethylphenylcarbamate )-based CSP exhibited characteristic enantioseparation and some chiral compounds were better resolved on this CSP than on Chiral-cel OD. The chiral recognition abilities of the obtained CSPs were increased with the decrease of the portion of isopropanol in the mobile phase and relatively high enantioseparation was obtained with the mobile phase of hexane-isopropanol ( 95: 5, v/v ). The obtained amylosic phase demonstrated slightly higher chiral resolving ability than the cellulosic one for the test racemates. In addition, it was revealed that the enantioseparations of the cellulosic and amy-losic CSPs were complementary.关键词
