Abstract
In the production of xylose, vegetable material containing hemicelluloses, e.g. fir chips, beechwood chips, detanninised chestnut wood, bagane, is pressed, if necessary, to reduce its moisture content to 45% or less and is subjected, e.g. in a continuous digester, to the action of an amount of hydrochloric acid not greater than it can completely absorb, at from 40 to 90 DEG C. for from 2 to 48 hours, the material being then pressed to recover concentrated pure xylose solution; thereafter it is washed, e.g. with water or with dilute xylose solution recovered from a second wash, and further pressed, the resultant solution being concentrated and purified, and treated to recover hydrochloric acid.
