Utilization of the entire lignocellulose is essential for sustainable and cost-effective biorefineries, but it is hindered by a trade-off between efficient carbohydrate utilization and lignin-to-chemical conversion yield. Here, the authors report a mild lignocellulosic fractionation process using aqueous diethylamine which produces a carbohydrate fraction susceptible to enzymatic hydrolysis and a high-quality lignin that delivers high monomer yields upon catalytic amination and depolymerization.
