Enantioseparation of 38 Racemates on Four Chiral Columns in High Performance Liquid Chromatography / 分析化学

ABSTRACT

The enantioseparations of 38 racemates on Chiralcel OD, Chiralpak AD, Chiralpak IA and(S, S)-Whelk-01 were presented by HPLC. Those enantiomers come from the amines, alcohols, ethers, ketones, aromatic derivatives, heterocyclic compounds, amide acids and medicines etc. With the mobile phase of n-hexane)/isopropanol(90∶ 10, V/V), n-hexane/isopropanol/trifluoracetic acid(90∶ 10∶ 0.2, V/V) or n-hexane/isopropanol/triethylamine(90∶ 10∶ 0.2, V/V), over 70% enantioseparations were obtained for OD, AD and IA columns). The order of enantioseparation selectivity for four columns was OD>AD>IA>(S,S)-Whelk-01, and among those columns there was a big chiral discriminating complementarity. This investigation was useful for choosing chiral columns to separate chiral compounds.
