Application



  • Characterization of Miscanthus giganteus lignin isolated by ethanol organosolv process under reflux condition: Hydrochloric acid plays a key role in the organosolv process to isolate lignin from Miscanthus giganteus, which is critical for the development of bio-based chemicals and materials (Bauer et al., 2012).
