Abstract: The conversion of lignocellulose into its building blocks and their further transformation into valuable platform chemicals (e.g. furfural) are key technologies to move towards the use of renewable resources. This paper explores the disentanglement of lignocellulose into hemicellulose‐derived sugars, cellulose and lignin in a biphasic solvent system (water/2‑methyltetrahydrofuran) using phosphoric acid as recyclable catalyst. Integrated with the biomass fractionation, in a second step hemicellulose‐derived sugars – mainly xylose – are converted to furfural, which is in situ extracted into 2‑methyltetrahydrofuran with high selectivity (70 %) and yield (56 wt%). To further increase the economic feasibility of the process, a downstream and recycling strategy enables recovery of phosphoric acid without loss of process efficiency over four consecutive cycles. This outlines a more efficient and sustainable use of phosphoric acid as catalyst, as its inherent costs can be significantly lowered.
