| description | A process is described for the preparation of water-soluble cellulose hydrolysis products The process comprises admixing cellulose with an ionic liquid capable of solvating or dissolving at least some of the cellulose, said ionic liquid being a compound comprised solely of cations and anions and which exists in a liquid state at a temperature at or below 15O °C, and in which the anions are selected from sulfate, hydrogen sulfate and nitrate; and treating the resulting solvate or solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25 °C.
L'invention concerne un procédé de préparation de produits hydrosolubles d'hydrolyse de la cellulose. Le procédé comprend le mélange de cellulose avec un liquide ionique capable de solvater ou de dissoudre au moins une partie de la cellulose, ledit liquide ionique étant un composé constitué uniquement de cations et d'anions et qui existe à l'état liquide à une température inférieure ou égale à 150 °C, lesdits anions étant choisis parmi sulfate, hydrogénosulfate et nitrate ; et le traitement du solvate ou de la solution résultante avec un acide en présence d'eau, ledit acide ayant un pKa dans l'eau inférieur à 2 à 25 °C. |
