The present application discloses: A method for the preparation of 2,5- (hydroxymethyl)furaldehyde from fructose with specific organic solvents. A method for the preparation of 2,5-(hydroxymethyl)furaldehyde from fructose with an acid catalyst. A method for the preparation of 2,5- (hydroxymethyl)furaldehyde from fructose with a with a two-phase organic solvent system. A method for the preparation of a 2,5- (hydroxymethyl)furaldehyde derivative from fructose. A method for the preparation of levulinic acid from fructose. A method for the preparation of 2,5-bis-(hydroxymethyl)furan from 2,5-(hydroxymethyl)furaldehyde.
La présente invention se rapporte à un procédé consistant à utiliser une source de fructose convenable sur le plan industriel pour effectuer une réaction de déshydratation visant à convertir un glucide en un dérivé furanique. L'invention a également trait à des procédés d'extraction. Dans ses modes de réalisation, l'invention permet d'améliorer les procédés connus de production de dérivés furaniques.
