Abstract

L'invention concerne la production d'une solution de xylose à partir de matières contenant du xylane et qui, à l'état sec, sont très absorbantes. On traite cette matière par arrosage de pulvérisation d'une solution acide ou à l'aide dune vapeur d'acide (de manière que la matière contienne assez de solution d'acide pour l'hydrolyse subséquente mais ne soit pas totalement imprégnée) l'on chauffe jusqu'à la température d'hydrolyse puis l'on effectue l'extraction, par lavage à contre-courant, du xylose formé. On peut ainsi traiter notamment des résidus de plantes annuelles et de bois. Le xylose ou sucre de bois peut servir en tannage, en teinture, pour l'alimentation des diabétiques ou pour des épreuves de diagnostic.
