Description/Abstract Solutions of D-glucose in dilute sulfuric acid were allowed to react under time and temperature conditions which simulated the production of glucose from cellulose.^Under these conditions, glucose undergoes a number of reactions including isomerization, dehydration, transglycosidation, polymerization, and anhydride formation.^The specific interest in this report was to investigate the reversible reactions which form ``reversion products``.^These products, which include di- and tri-saccharides, anhydrides, and glucosides, provide a protection for glucose from decomposition, but the products are not fermentable.^The reactions were studied at 180 and 230/sup 0/C for various times and concentrations.^The products were categorized as reducing or nonreducing, and the total glucose produced by secondary hydrolysis from the nonfermentable products was determined.^Depending on conditions, these products may constitute more than 20% of the potentially available glucose.^A preliminary study was made on D-xylose, which will form reversion products at xylose concentrations above 20%.^17 references, 2 figures, 6 tables.
