| Abstract: | A method for the enantioseparation of 2,5-Hexanediol by capillary gas chromatography with precolumn derivatization was proposed.2,5-Hexanediol enantiomers were derivatized with S-(-)-phenylethyl isocyanate and the baseline separation of the resulting derivatives was achieved by gas chromatography.The main factors including the flow rate of carrier gas and the program temperature in influencing the separation were also discussed.A fast,simple and accurate method for determination of the enantiomeric excess of 2,5-hexanediol was established. |
