Title

(EN) PRODUCTION OF CRYSTALLINE CELLULOSE

(FR) PRODUCTION DE CELLULOSE CRISTALLINE

Abstract

(EN) A method of producing crystalline cellulose from a cellulosic material includes the step of reacting the cellulosic material in an aqueous slurry comprising a transition metal catalyst and a hypohalite solution.

(FR) Cette invention concerne un procédé de production de cellulose cristalline à partir d'une matière cellulosique comprenant l'étape de réaction de la matière cellulosique dans une suspension aqueuse épaisse comprenant un catalyseur de métal de transition et une solution d'hypohalite.
