✦ Synopsis
A novel procedure is proposed for the calculation of Gibbs energy corresponding to enantiospecific interactions of 2-(2,4-dinitrophenoxy)-, 2-phenoxy-, and 2-halogen-n-pentane enantiomers with a -cyclodextrin (ChirasilDex) stationary phase under gas chromatographic conditions. This energy is calculated from retention data as a difference between the Gibbs energy of an enantiomer and its corresponding achiral congener. The procedure for the determination of 2-(2,4-dinitrophenoxy)-, 2-phenoxyand 2-halogen-n-pentane achiral congener retention data is discussed in detail.
