26 Claims

1. 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.
