| 英文摘要 | in this paper, the enthalpy-entropy compensation effect in the enantiomeric separation by modified cyclodextrins (cd) and diamide chiral stationary phase (csp) gas chromatography was investigated using the method of plotting delta(delta h) versus delta(delta g)(thm) combined with t-test statistic analysis. the investigated racemates cover alpha-phenylethylamine and its analogs, 2-alkylamines, chiral acyclic alcohols, halogenated arylethanediol-1, 2-diperfluoropropionates, amino acid and its analogs, and two series of compounds containing chloro and bromo substituents. from the compensation analysis results, the effects of the diluent composition in the investigated chiral stationary phases, the size and. the modified groups on investigated cyclodextrins, the derivatization methods and the groups attached to the stereocenters on enantiomeric separation mechanisms were all discussed. |
