Title (EN) TREATMENT OF PULP TO PRODUCE MICROCRYSTALLINE CELLULOSE
(FR) TRAITEMENT DE PATE A PAPIER EN VUE DE PRODUIRE DE LA CELLULOSE MICROCRYSTALLINE
Abstract: front page image
(EN)In one embodiment of the invention is disclosed a process for the production of microcrystalline cellulose comprising hydrolyzing pulp with a sufficient amount of active oxygen in an acidic environment in a one step process; and recovering the microcrystalline cellulose; wherein said recovered microcrystalline cellulose has a color lightness (L*) greater than the color lightness (L*) of the pulp starting material.
(FR)Dans l'un des modes de réalisation de la présente invention, on décrit un procédé de production de cellulose microcrystalline comprenant l'hydrolyse de la pâte à papier avec une quantité suffisante d'oxygène actif dans un environnement acide lors la phase unique du procédé, et la récupération de la cellulose microcrystalline, cette cellulose microcrystalline récupérée présentant une clarté de couleur (L*) supérieure à la clarté de couleur (L*) de la pâte à papier de départ.
