A technique for determining the enantiomeric composition of 2-octanol and α -phenylethylamine with the use of gas chromatography on optically inactive stationary phases is proposed. The technique is based on the formation of symmetrical 1 diastereomeric derivatives upon the interaction of enantiomers with bifunctional achiral reagents: dimethyldichlorosilane, bromochloromethane, and dibromoethane. The reagents were chosen from the viewpoint of the synthesis of diastereomers with a minimum distance between the chiral centers. This minimum distance is responsible for a difference in the energies of interaction of the derivatives with the stationary liquid phase, which is sufficient for the separation of these derivatives.
