摘要: 合成了纤维素-三(苯甲酯)(CTB)和纤维素-三(氨基苯甲酸酯)(CTPC)衍生物,并涂敷于自制的球形硅胶上(5μm,13nm),制备了用于高效液相色谱手性拆分的固定相.考察了涂敷量、流动相等因素对手性拆分的影响,测定了一个不对称氢化酯化反应的对映体过剩值(e.e.值).

Abstract: Optical resolution of a range of racemic compounds was investigated using cellulose tribenzate and trisphenylcarbamate coated onto a small-partial spherical organosilane modified silica. The influence on chiral discrimination of factors such as coated loadings and mobile phase was performed. The loadings of 15% on the support gave the best results. The regioselectivity of an asymmetric hydroesterification of styrene was determined by HPLCusing a chiral stationary phase(CTPC-CSP). Asatisfactory result had been obtained on CTPCchiral column with n-hexane/2-propanol(98/2 in volume ratio) as mobile phase.

Key words: HPLC, Cellulose derivatives, Chiral stationary phase, Optical resolution, Asymmetric hydroesterification
