Liquid Chromatographic Resolution of Enantiomeric 1,1’-Bi-2-naphthol and Phenylsuccinic Acid on a Coated Reversed-phase Column with 2,6-O-Butyled β-Cyclodextrins


利用合成的 2 ,6 O 丁基 β 环糊精动态涂渍反相色谱柱 ,β CD在C18和C8填料表面“永久”吸附形成一手性固定相 ,以联萘二酚和苯基琥珀酸为对象进行高效液相色谱拆分研究。当采用乙腈 水 (体积 33∶6 7)流动相时 ,联萘酚对映体在 2 ,6 O 丁基 β 环糊精涂渍ExsilODS柱上分离的容量因子分别为 14 .2 35和 15 6 2 9,分离选择性为 1.0 98;而采用乙腈 0 .1%三氟乙酸水溶液 (体积比 15∶85 )流动相时 ,苯基琥珀对映体的容量因子分别为 7.0 2 3和 8.14 9,分离选择性为 1.16 0。文中优化了色谱条件 ,探讨了有关的手性色谱拆分机理。该法可用于实际样品的对映体纯度测定。国家自然科学基金资助项目 (No .2 983 2 0 2 0
