Lignin Hydrogenolysis: Phenolic Monomers from Lignin and Associated Phenolates across Plant Clades

The chemical complexity of lignin remains a major challengeforlignin valorization into commodity and fine chemicals. A knowledgeof the lignin features that favor its valorization and which plantsproduce such lignins can be used in plant selection or to eng ...

Selecting Suitable Near-Native Lignins for Research

Jeremy Luterbacher

There are several methods to isolate near-native lignins, including milled-wood lignin, enzymatic lignin, cellulolytic enzyme lignin, and enzymatic mild-acidolysis lignin. Which one is the most representative of the native lignin? Herein, near-native ligni ...

Direct conversion of lignin to functionalized diaryl ethers via oxidative cross-coupling

Paul Joseph Dyson, Mingyang Liu

Efficient valorization of lignin, a sustainable source of functionalized aromatic products, would reduce dependence on fossil-derived feedstocks. Oxidative depolymerization is frequently applied to lignin to generate phenolic mono- mers. However, due to th ...

Controlling lignin solubility and hydrogenolysis selectivity by acetal-mediated functionalization

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Existing lignocellulosic biomass fractionation processes produce lignin with random, interunit C-C bonds that inhibit its depolymerization and constrain its use. Here, we exploit the aldehyde stabilization of lignin to tailor its structure, functionality, ...

Guidelines for performing lignin-first biorefining

Jeremy Luterbacher, Feng Wang

The valorisation of the plant biopolymer lignin is now recognised as essential to enabling the economic viability of the lignocellulosic biorefining industry. In this context, the "lignin-first" biorefining approach, in which lignin valorisation is conside ...

Aldehyde-Assisted Lignocellulose Fractionation Provides Unique Lignin Oligomers for the Design of Tunable Polyurethane Bioresins

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Raymond Gérard Buser, Chloé Wegmann

Thanks to chemical stabilization, aldehyde-assisted fractionation (AAF) of lignocellulosic biomass has recently emerged as a powerful tool for the production of largely uncondensed lignin. Depolymerization of AAF lignin via ether deavage provides aromatic ...

Fractionation of lignocellulosic biomass to produce uncondensed aldehyde-stabilized lignin

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Graham Reid Dick

Lignin is one of the most promising sources of renewable aromatic hydrocarbons. Current methods for its extraction from lignocellulosic biomass—which include the kraft, sulfite, and organosolv processes—result in the rapid formation of carbon–carbon bonds, ...

Preventing Lignin Condensation to Facilitate Aromatic Monomer Production

Jeremy Luterbacher, Wu Lan

Lignin is the most abundant aromatic polymer in nature and as such is an attractive source of aromatic molecules. Efficient lignin utilization will also likely play a key role in the economic success and sustainability of biomass valorization schemes. Howe ...

Single-step conversion of lignin monomers to phenol: Bridging the gap between lignin and high-value chemicals

Paul Joseph Dyson, Ning Yan

Transformation of lignin into high-value chemicals is hampered by the complexity of monomers obtained from lignin depolymerization. Here we report a strategy, composed of hydro-demethoxylation and de-alkylation reactions, that is able to chemically converg ...

All natural cork composites with suberin-based polyester and lignocellulosic residue

Véronique Michaud, Hugo De Oliveira

Suberin is an aromatic-aliphatic cross-linked polyester structure which constitutes cell wall structures of cork. It is particularly interesting for its use of monomeric compounds towards renewable bio-based polymers. In this study, the extraction of suber ...
