| titleOfInvention | PROCESS FOR THE PRODUCTION AND SEPARATION OF 5-HYDROXY METHYL FURFURAL WITH QUATERNARY AMMONIUM SALTS |
| abstract | The present invention relates to a process for the production and separation of 5-hydroxy methyl furfural (HMF), which comprises the steps of: (1) dehydrating at least one saccharide selected from the group consisting of 6-atom monosaccharides carbon and disaccharides, oligosaccharides and polysaccharides formed from units that have 6 carbon atoms, or mixtures thereof, in the presence of water and at least one quaternary ammonium salt, at a temperature between 80 and 130 ° C, obtaining a reaction mixture comprising the quaternary ammonium salt, HMF and any unreacted saccharide; and (2) subjecting said reaction mixture to at least one membrane separation operation selected from the group consisting of nanofiltration, reverse osmosis, electrodialysis, and their combinations, obtaining an aqueous permeate comprising HMF and a retentate comprising the quaternary ammonium salt, in which both the dehydration operations of step (1) and the separation of step (2) are carried out in the absence of organic solvents. |
