Title (EN) HEMICELLULOSE COMPOSITIONS
(FR) COMPOSITIONS D'HÉMICELLULOSE
Abstract: front page image
(EN)Hemicellulose compositions are prepared by treating a cellulosic material with an extractant comprising a cellulose solvent and co-solvent. The hemicellulose compositions preferably comprise from 55 to 99 wt.% xylan and have distinct molecular weights, elemental metal ions, and intrinsic viscosities when compared to known hemicellulose compositions.
(FR)Cette invention concerne des compositions d'hémicellulose préparées par traitement d'une matière cellulosique au moyen d'un agent d'extraction comprenant un solvant pour cellulose et un co-solvant. Les compositions d'hémicellulose selon l'invention comprennent de préférence entre 55 et 99 % en poids de xylane et présentent des poids moléculaires, des ions métalliques élémentaires, et des viscosités intrinsèques qui les distinguent de compositions d'hémicellulose connues.
