7he present invention relates to a method of producing xylose by chromatographic separation of the xylose from a sulphite cooking liquor containing for example xylose and xylonic acid. The xylose yield of the separation is affected by the xylonic acid and xylose content in the cooking liquor used in the separation and the amount of base cation used in the sulphite cooking.
La présente invention concerne un procédé de production de xylose par séparation chromatographique du xylose d'une lessive de cuisson au sulfite renfermant notamment du xylose et de l'acide xylonique. Le rendement en xylose de cette séparation dépend de la teneur en acide xylonique et en xylose dans la lessive de cuisson utilisée dans la séparation, et de la quantité de cation de base utilisée dans la cuisson au sulfite.
