Title (EN) MODIFIED LIGNIN AND SEPARATION METHODS
(FR) LIGNINE MODIFIÉE ET PROCÉDÉS DE SÉPARATION
Abstract:
(EN) A method of processing a lignocellulosic feedstock includes heating the lignocellulosic feedstock in a solvent mixture comprising an acid and at least 80% by volume of n-butanol to produce a reaction mixture including a butylated lignin. A butylated lignin product wherein at least 85% of the β-Ο-4 linkages include n-butyl ether groups can be prepared. Cellulose and butylated hemicellulose products can also be obtained.
(FR) La présente invention concerne un procédé de traitement d'une charge lignocellulosique comprenant le chauffage de la charge lignocellulosique dans un mélange de solvants comprenant un acide et au moins 80 % en volume de n-butanol pour produire un mélange réactionnel comprenant une lignine butylée. Un produit de lignine butylée dans lequel au moins 85 % des liaisons bêta-O-4 comprennent des groupes éther de n-butyle peuvent être préparés. Des produits d'hémicellulose butylé et de cellulose peuvent également être obtenus.
