摘要: Ionic liquids are attractive reaction media for the solubilisation and depolymerisation of lignin into value-added products. However, mechanistic insight related to cleavage specific linkages relevant efficient in such solvents is still lacking. This study presents important scission most abundant β-O-4 motif Bronsted acidic ionic liquids. Using model compounds, products were identified undesired side reactions examined carefully. Stabilization reactive intermediates was achieved comprising both function stabilized nanoparticles that comprise hydrogenation activity order suppress reactions. Especially, situ aldehyde intermediate originating from acid-catalysed beta-O-4 compounds more stable alcohols investigated. first time have been systematically targeted these multifunctional relation depolymerization.
