- •
Bench scale ionic liquid extraction of wood pulp yielded dissolving pulp quality pulp.
- •
Coproduction of a high quality hemicellulose fraction was demonstrated.
- •
Overall yield in the fractionation was high with 95.5 wt.%.
- •
Films of the modified hemicellulose fraction showed excellent barrier properties.
- •
The films had in addition good strength properties.
