    Abstract: A process for preparing furan-2,5-dicarboxylic acid is disclosed. The process includes the following steps: preparing or providing a starting mixture including 5-(hydroxy-methyl)furfural (HMF), 5,5′-[oxy-bis(methylene)]bis-2-furfural (di-HMF), and water; subjecting said starting mixture to oxidation conditions in the presence of an oxygen-containing gas and a catalytically effective amount of a heterogeneous catalyst including one or more noble metals on a support so that both HMF and di-HMF react to give furane-2,5-dicarboxylic acid in a product mixture also including water and oxidation by-products. The use of a catalyst is also disclosed, the catalyst including one or more noble metals on a support as an heterogeneous oxidation catalyst for catalyzing in an aqueous starting mixture the reaction of both HMF and di-HMF to furane-2,5-dicarboxylic acid.

    Abstract: Method for producing 5-hydroxymethylfurfural (HMF), wherein a) solutions (hereinbelow called starting solution) which comprise a hexose and an organic solvent with a boiling point greater than 200° C. (at standard pressure) (for short called high-boiling component), and steam are fed to a reaction vessel, b) in the reaction vessel, a conversion of the hexose to HMF takes place in the presence of steam with the simultaneous distillative removal of the HMF and c) as distillate, an aqueous, HMF-comprising solution (hereinbelow called distillate) is obtained.
