FIELD: chemistry.
SUBSTANCE: invention relates to a method for selective production of oxidised furan derivatives based on 5-hydroxymethyl-2-furfurol of formula
,
which consists in that the oxidation method is carried out continuously in a stream in a reactor, in which there are means for varying reaction parameters, in a solvent which is water, in the presence of a cosolvent, which is a dipolar aprotic solvent, and where said oxidised furan derivative is selected from 5-hydroxymethylfuran-2-carboxylic acid of formula, 2,5-diformylfuran of formula, 5-formylfuran-2-carboxylic acid of formula and 2,5-furan dicarboxylic acid of formula.
EFFECT: technical result is a novel method of producing oxidised furan derivatives from 5-hydroxymethyl-2-furfurol with high selectivity and output of the product.
