CHEMICALS FROM RENEWABLE RESOURCES: HEMICELLULOSE BEHAVIOR DURING ORGANOSOLV DELIGNIFICATION OF SOUTHERN YELLOW PINE

Abstract

Batch delignification of southern yellow pine using aqueous solutions of ethanol and 1-butanol have been studied at a temperature of 175°C. The extent of delignification, hemicellulose hydrolysis of the pulp, and monosaccharide appearance in solution are reported. From these data the relationship of bulk delignification, hemicellulose behavior and solvent selectivity can be used to better explain pulp yield from alcohol: water treatment processes,
