Abstract

We suggest for the first time the use of γ-valerolactone (GVL)/H2 O as solvent and reaction medium for the fractionation of wood to recover pure cellulose, uniform sugar components from hemicellulose, and a pure lignin fraction. The yield of the pulp residue could reach 40.3 % with a high cellulose purity of 90.3 %.
