摘要: The present invention discloses a biphasic solvent system for converting biomass to prepare 2,5-hexanedione and a one-pot process for catalytically converting biomass to prepare 2,5-hexanedione with said biphasic solvent system. The process comprises: contacting and reacting a biomass raw material with a hydrogenation catalyst using hydrogen gas as a hydrogen source in a heterogeneous system formed from an organic solvent, an inorganic salt and water to obtain 2,5-hexanedione; the hydrogenation catalyst comprises a hydrogenation active component and a support, wherein said support is selected from one or more of hydrophobic active carbon and graphene. The process of the present invention can achieve efficient conversion of biomass without the participation of acid catalysts, and have a very high selectivity for the product 2,5-hexanedione.
