“…Until now, the commercial furfural process has suffered from disadvantages such as furfural loss, equipment corrosion, and high-energy consumption [3]. Solid acid catalysts successfully solved some drawbacks of liquid catalysts, such as separation and recycling et al [4][5][6]. Wang et al applied sulfonated palygorskite solid acid catalyst (PAL-SO 3 H) prepared by a mechanochemical process to biomass-derived xylose into furfural, and 87% of furfural yield with 96% selectivity was achieved [7].…”

Dehydration of Xylose to Furfural over Imidazolium-Based Ionic Liquid with Phase Separation

et al. 2021

An environmentally friendly catalyst and task-specific ionic liquid (IL), 1-(4-sulfonic acid) butyl-3-cetyl-2-methyl imidazolium hydrogen sulfate, was applied to the dehydration of xylose to furfural. Its structure was determined by FT-IR, 1H NMR technologies. The solubility of IL in water changed with the temperature, and had the advantages of homogeneous and heterogeneous catalysts. At the given conditions, xylose conversion of 95.3% and furfural yield of 67.5% were achieved over IL.
