Abstract: Depending upon the conditions of base-catalyzed aldolization of trioses D,L-fructose, D,L-sorbose, and D,L-dendroketose are formed in different proportions. A method has been developed for the determination of thus produced ketohexoses using gas chromatography of per-0 -TMS derivatives of the sugars themselves and of the polyols derived therefrom. The aldolization products can also be separated by paper chromatography, and, on a preparative scale, by column chromatography on cellulose. Based on the analytical study, an attempt to explain the nature of dendroketose is also described.
