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)
