Conversion of Biomass Sugars to Butyl Levulinate over Combined Catalyst of Solid Acid and other Acid

Abstract:

SO₄²⁻/SnO₂-ZrO₂ catalyst, organic acids, inorganic acids and sulfates have been applied for the alcoholysis of sugars to butyl levulinate using n-buthanol as solvent and reactant. The combined effect of solid acid and H₂SO₄ showed a high catalytic activity for the selective conversion of cellulose to butyl levulinate at 200 °C, whereas the glucose yielded around 40 mol% butyl levulinate. The oxalic acid and CuSO₄ also showed great activity towards the cellulose alcoholysis.
