采用纤维素-三(3,5-二甲基苯基氨基甲酸酯)涂敷型手性固定相(Chiralcel OD柱)、直链淀粉-三(3,5-二甲基苯基氨基甲酸酯)涂敷型手性固定相(Chiralpak AD柱)、直链淀粉-三(3,5-二甲基苯基氨基甲酸酯)键合型手性固定相(Chiralpak IA柱)和Pirkle型的(S,S)-Whelk-01手性固定相对38种外消旋体化合物进行手性拆分。实验结果表明,4种固定相的手性识别能力为:OD〉AD〉IA〉(S,S)-Whelk-01,OD固定相的手性识别率达到60%,并且它们之间的手性识别性能还具有一定的互补性。本研究对4种常用手性固定相的拆分能力进行了对比,为拆分手性化合物时有的放矢地选择手性固定相提供了参考。
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.
