Selective depolymerization of cellulose

Abstract

According to an example aspect of the present invention, there is provided a selective method for producing cellulose. The method comprising the steps of providing cellulose, reducing crystallinity of the cellulose by pretreatment to obtain a pretreated cellulose, oxidizing the pretreated cellulose, and subjecting the oxidized cellulose to depolymerization. Further, the present invention concerns a cellulose obtained by such method and a cellulose having controlled molecular weight, as well as uses of such celluloses.
