摘要
正相模式下研究了安息香、氢化安息香及α-苯乙醇在苯基甘氨酸型手性固定相Ch irex 3001上的拆分,探讨了流动相组成及柱温对手性拆分效果的影响。当流动相为正己烷∶1,2-二氯乙烷∶乙醇(体积比)=83.5∶15∶1.5,流速为1.0 mL/m in,柱温为25℃时,三者的分离因子分别为1.04、1.11和1.02。此方法可用于氢化安息香等光学纯度的测定。
Resolution of benzoin, hydrobenzoin and α-phenethyl alcohol with （R）-phenylglycine based chiral stationary phase（ Chirex 3001 ） in the normal-phase conditions were studied. The effects of the mobile phase composition and the column temperature on the chiral resolution were investigated. When nhexane： 1,2-dichloroethane： ethanol（ volume ratio, 83.5： 15：1.5 ）was used as mobile phase at a flow rate of 1.0 mL/min, the column temperature 25℃, the separation factors were 1.04,1.11 and 1.02 respectively for these three compounds. The method can be used to determine optical purity of hydrobenzoin.
