Abstract
Reaction products of d-glucitol with acetone and zinc chloride were studied by gas chromatography and gas chromatography—mass spectrometry. Complete separation of the reaction mixtures was achieved on two capillary columns coated with Carbowax 20M and SE-30. The methylene unit values were determined for eleven derivatives of d-glucitol acetals. Correlations were found between the methylene units of the acetals on stationary phases of different polarities and their structures. An attempt is made to explain the relationship between the elution order and the preferred conformers of the d-glucitol acetals. The structures of all derivatives were confirmed by mass spectrometry.
