resumo
This short review encompasses the last relevant studies that have been unveiling efforts to increase the efficiency of lignin depolymerization and functionalization into bio-based platform chemicals. One of the drawbacks upon lignin depolymerization is the undesired condensation reactions (repolymerization) that negatively affect the yields of lignin monomers. Some recent technologies have demonstrated to be effective on protecting lignin from repolymerization and enhancing depolymerization efficiency. Furthermore, functionalization of lignin aromatic monomers is needed to move towards a more sustainable chemical industry. As major example, the amination of lignin depolymerization products stands as hot research topic for future lignin valorization, the latest achievements being addressed in this review.
