Title (EN) CELLULOSE ESTERS AND THEIR PRODUCTION IN CARBOXYLATED IONIC LIQUIDS
(FR) ESTERS DE CELLULOSE ET LEUR PRODUCTION DANS DES LIQUIDES IONIQUES CARBOXYLÉS
Abstract: front page image
(EN)Ionic liquids and cellulose ester compositions and processes and apparatus for producing ionic liquids and cellulose esters. Cellulose esters can be produced by dissolving cellulose in carboxylated ionic liquids and thereafter contacting the cellulose solution with at least one acylating reagent. Cellulose esters produced via the present invention can comprise ester groups that originate from the carboxylated ionic liquid and/or the acylating reagent.
(FR)L'invention concerne des compositions de liquides ioniques et d'esters de cellulose et des procédés et un appareil pour produire des liquides ioniques et des esters de cellulose. Les esters de cellulose peuvent être produits par dissolution de cellulose dans des liquides ioniques carboxylés, puis mise en contact de la solution de cellulose avec au moins un réactif d'acylation. Les esters de cellulose produits par la présente invention peuvent comprendre des groupes ester ayant pour origine le liquide ionique carboxylé et/ou le réactif d'acylation.
