Procedimientos para remover hemicelulosa que comprende extraer el material celulosico con un extrantante, oxido de amina y un no solvente, y separar la hemicelulosa extraida para formar un producto celulosico.

摘要

A method for treating a cellulosic material comprising extracting the cellulosic material with an extractant to selectively extract hemicellulose therein and separating the extracted hemicellulose to form a cellulosic product comprising less hemicellulose than the cellulosic material. The extractant comprises an amine oxide and a non-solvent. The cellulosic product retains the cellulosic fiber morphology.
