资源简介：
A process for the production of a non-derivatized nanocellulose material from a cellulosic fibrous material， comprising the steps of providing a suspension of cellulosic fibrous material in a continuous phase of a non-aqueous process liquid comprising a swelling agent and a processing solvent; forming a suspension of swollen cellulosic fibrous material in a continuous phase of non-aqueous process liquid; forming a suspension of cellulosic fibrous material in a continuous phase of processing solvent; forming a dispersion of non-derivatized nanocellulose material in a continuous phase of a processing solvent; isolating the non-derivatized nanocellulose material， characterized in that the swelling agent is a low-transition-temperature mixture (LTTM) and in particular a deep eutectic solvent and said low-transition-temperature mixture and in particular said deep eutectic solvent is soluble in the processing solvent and wherein the processing solvent is non-solubilizing for the cellulosic fibrous material and the non-derivatized nanocellulose material.
