Abstract: Abstract For the valorization of lignin, it is important and a great challenge to prevent the negative impact of phenolic hydroxyl (Ph-OH) on lignin pyrolysis by blocking the Ph-OH. Herein, lignin samples with different oxypropylation… read more here.

Abstract: Lignin, one of the main components of lignocellulose, can be used as an alternative to chemical polyols in the production of polyurethane because of its abundant phenolic and alcohol hydroxyls. Traditionally, lignin is directly applied… read more here.
