AI Article Synopsis
- - Cellulose triacetate was created by chemically modifying lignocellulosic biomass using a special acetylating agent (isopropenyl acetate, IPA) in a liquid solvent that helps dissolve the biomass (1-ethyl-3-methylimidazolium acetate, EmimOAc).
- - The process involved treating sugar-cane bagasse at a mild temperature (80 °C) for a short period (30 minutes) to allow for effective acetylation.
- - This method produced a high-quality cellulose triacetate with a significant degree of substitution (DS of 2.98) and a glucose purity of about 90%, along with some lignin acetate as a byproduct.
Article Abstract
Cellulose triacetate was synthesised by the transesterification reaction of mild acid-pretreated lignocellulosic biomass with a stable acetylating reagent (isopropenyl acetate, IPA) in an ionic liquid (1-ethyl-3-methylimidazolium acetate, EmimOAc) which enabled the dissolution of lignocellulose as well as the organocatalytic reaction. The homogeneous acetylation of pretreated sugar-cane bagasse was carried out under mild conditions (80 °C, 30 min), and the subsequent reprecipitation processes led to enriched cellulose triacetate with a high degree of substitution (DS; 2.98) and glucose purity (∼90%) along with production of lignin acetate.
