Prehydrolysis of aspen wood with water and with dilute aqueous sulfuric acid
Edward L. Springer, John F. Harris · 1982
Water prehydrolysis of aspen wood was com pared with 0.40% sulfuric acid prehydrolysis at a reaction temperature of 170°C. Acid prehydrolysis gave much higher yields of total anhydroxylose units in the prehydro lyzate and removed significantly less anhydroglucose from the wood than did the water treatment. At maximum yields of total anhydroxylose units in the prehydrolyzates, much more monomeric xylose was present in the acid prehydro lyzate than in the water prehydrolyzate.
