The present invention is directed to a process for the synthesis of 2,5-furandicarboxylic acid (FDCA) comprising the steps of: (1) oxidising an aqueous solution of 5 hydroxymethylfurfural (HMF) in the presence of molecular oxygen, of a heterogeneous catalyst comprising ruthenium and of a strong base at a temperature above 100° C., obtaining a reaction product in aqueous solution comprising a salt of FDCA acid; (2) separating said heterogeneous catalyst from said reaction product in aqueous solution, and (3) re-using said heterogeneous catalyst in the oxidation reaction in step (1).

The present invention relates to a process for the synthesis of 5-hydroxymethyl furfural (HMF) comprising the steps of: 1) dehydrating at least one saccharide selected from monosaccharides having 6 carbon atoms and disaccharides, oligosaccharides or polysaccharides formed from units having 6 carbon atoms or mixtures thereof in the presence of at least one quaternary ammonium salt RR'NX; in which: &#x2014;R, which is the same or different, represents a C-Csubstituted or unsubstituted alkyl group; &#x2014;R&#x2032; belongs to the group consisting of: hydrogen, C-Csubstituted or unsubstituted alkyl group, monocyclic substituted or unsubstituted aryl group; &#x2014;Xrepresents an anion selected from chloride, bromide, iodide, fluoride, hydroxide, BFand PF; at a temperature of between 80 and 120&#xb0; C., removing water from the reaction medium (dehydration stage) and obtaining a reaction mixture comprising the quaternary ammonium salt, HMF, any unreacted saccharide and having a water content of less than 30% by weight relative to the weight of the product HMF; 2) separating HMF from the said reaction mixture (separation stage).

Process for the production and isolation of 5-hydroxymethylfurfural

This invention relates to a process for the synthesis of 5-hydroxymethylfurfural (HMF) from saccharides. In particular this invention relates to a process for the dehydration of monosaccharides having 6 carbon atoms (hexoses), disaccharides, oligosaccharides, and polysaccharides to yield highly pure 5-hydroxymethylfurfural (HMF) in high yield.
