  • Patent number: 11697642
    Abstract: The present invention relates to a method for the production of 5-hydroxymethylfurfural (HMF), which converts a fructose-containing component using a catalytically active anolyte fraction, which has been produced by electrolysis of water, at a temperature of 90 to 200° C. and for obtaining an HMF-containing product mixture, wherein advantageously a high HMF selectivity is achieved with significantly lower by-product formation.
    Type: Grant

  • Patent number: 11548863
    Abstract: The present invention relates to a method for the production of 5-hydroxymethylfurfural (HMF), which converts a fructose-containing component using a catalyst system comprising a solution of a salt and acid mixture at a temperature of 90 to 200° C. and leads to obtaining an HMF-containing product mixture, wherein advantageously a high HMF selectivity with significantly lower by-product formation is achieved at the same time.

  • Patent number: 10662167
    Abstract: The invention relates to a method for producing 5-hydroxymethylfurfural (HMF) in a continuous process, which leads to the obtainment of an HMF fraction, a carbohydrate/acid fraction, a fructose fraction, and a levulinic-acid and formic-acid fraction and advantageously makes it possible, because of the purity of the obtained fractions, to return the fructose fraction obtained by means of the method directly to the production process and to use the other fractions in further-processing processes without the need for complex, additional purification steps.
