Abstract:
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.
