FIELD: pharmaceuticals.
SUBSTANCE: invention relates to a one-pot method for obtaining the compound 5-HMF (5-hydroxymethylfurfural), which includes the following stages: i) the reaction of carbohydrates with oxalic acid dihydrate and inorganic acids in the presence of a two-phase solvent and carbon material at 110–160°C for 6–12 hours with vigorous stirring; ii) extracting the compound in the presence of a solvent; iii) drying the reaction mixture over Na2SO4 and then evaporating the solvent under reduced pressure to give 5-hydroxymethylfurfural.
EFFECT: efficient, highly selective and cost-effective method for obtaining 5-HMF from carbohydrates.
