| titleOfInvention | Process for the production and isolation of 5-hydroxymethylfurfural |
| abstract | 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 R 3 R'N + X - ; in which: - R, which is the same or different, represents a C 1 -C 16 substituted or unsubstituted alkyl group; - R' belongs to the group consisting of: hydrogen, C 1 -C 16 substituted or unsubstituted alkyl group, monocyclic substituted or unsubstituted aryl group; - X - represents an anion selected from chloride, bromide, iodide, fluoride, hydroxide, BF 4 n - and PF 6 n - ; at a temperature of between 80 and 120°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). |
