      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.},
