RT Journal Article T1 Performance of 1-(3-sulfopropyl)-3-methylimidazolium hydrogen sulfate as a catalyst for hardwood upgrading into bio-based platform chemicals A1 Lopez Rodriguez, Mar A1 Rivas Siota, Sandra A1 Vila Babarro, Carlos A1 Santos Reyes, Valentín A1 Parajo Liñares, Juan Carlos K1 3303.03 Procesos Químicos K1 3310.05 Ingeniería de Procesos K1 3312.13 Tecnología de la Madera AB The acidic ionic liquid 1-(3-sulfopropyl)-3-methylimidazolium hydrogen sulfate ([C3SO3Hmim]HSO4) was employed as a catalyst for manufacturing polysaccharide-derived products (soluble hemicellulose-derived saccharides, furans, and/or organic acids) from Eucalyptus globulus wood. Operation was performed in aqueous media supplemented with [C3SO3Hmim]HSO4 and methyl isobutyl ketone, following two different processing schemes: one-pot reaction or the solubilization of hemicelluloses by hydrothermal processing followed by the separate manufacture of the target compounds from both hemicellulose-derived saccharides and cellulose. Depending on the operational conditions, the one-pot reaction could be directed to the formation of furfural (at molar conversions up to 92.6%), levulinic acid (at molar conversions up to 45.8%), or mixtures of furfural and levulinic acid (at molar conversions up to 81.3% and 44.8%, respectively). In comparison, after hydrothermal processing, the liquid phase (containing hemicellulose-derived saccharides) yielded furfural at molar conversions near 78%, whereas levulinic acid was produced from the cellulose-enriched, solid phase at molar conversions up to 49.5%.
