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.
Claims26
A method for the production of 5-hydroxymethylfurfural (HMF) comprising the steps:
- a) providing a fructose-containing component,
- b) producing a catalytically active anolyte fraction by electrolysis of water,
- c) mixing the fructose-containing component and the catalytically active anolyte fraction to obtain a reaction solution,
- d) converting the fructose present in the reaction solution to HMF at a temperature of 90° C. to 200° C. to obtain a liquid HMF-containing product mixture, and
- e) obtaining a liquid HMF-containing product mixture.
