Procedures for removal of hemicellulose, which involves removing the Cellulosic material with a extrantante, Ionic liquid and a non Solvent and Separating hemicellulose extracted to form a Cellulosic product

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.
