Abstract
Compounds obtained on acetonation of D-mannitol were studied by gas chromatography and gas chromatography-mass spectrometry. The separation of the reaction mixtures was achieved on capillary columns coated with Carbowax 20M or OV-101. Methylene unit values were determined for ten acetylated D-mannitol acetals. Correlations were found between the methylene units of the acetals and their structures on the stationary phases of different polarity. An attempt has been made to explain the relationship between the elution orders and preferred conformers of the acetals. The structures of the acetylated compounds were confirmed by mass spectrometry.
