Abstract (en)

[origin: WO2012127110A1] The invention relates to a process for preparing micro- and nanocrystailine cellulose material in the presence of an acid. More specifically, the invention relates to a process, in which the cellulose material is hydrolyzed in the presence of an acid in the gas phase while the moisture content of cellulose is between 1% and 80%, the cellulose material is surface-modified, and mechanically treated in order to obtain micro- and/or nanocrystailine cellulose material. The invention also relates to a cellulose product prepared by the said process and the use thereof in food and liquid crystal applications as well as in optical, cosmetic and medical applications.
