Enantiomer Separation of Cycloalkanols by Capillary Gas Chromatography on Cyclodextrin Phases
R. Reinhardt, W. Engewald, and U. Himmelreich, B. Christian and B. Koppenhoefer

The enantiomers of 14 mono-, di-, tri-, and tetramethyl cyclohexanols, 2-methylcycloheptanol, and 2-methylcyclooctanol are separated with capillary gas–liquid chromatography on permethylated a- and b-cyclodextrin, respectively, dissolved in the polysiloxane phase OV-1701. Thermodynamic data are determined in order to investigate the mode of interaction of the enantiomers with the two chiral stationary phases. Besides this, there is no apparent relationship between the differences in retention indices on chiral and achiral stationary phases and the thermodynamic data of interaction with the chiral selector.
