Abstract
Kinetics of the acetolysis and concomitant anomerization of ethyl 2,3, 4,6-tetra-O-acetyl-alpha- and -beta-D-glucopyranosides in a mixture of acetic anhydride, acetic acid, and sulfuric acid have been studied. T he progress of the reactions was followed by gas chromatography, and t he rate constants of the partial reactions were calculated on the basi s of the time-dependent product distributions obtained. The mechanisms of the reactions are discussed.
