Abstract

The shortage of fossil energy carriers demands the use of renewable and sustainable energy resources. Biomass has the potential to fulfill these needs. The chemical transformation of cellulose, being a main part of plant biomass, allows the production of a widespread variety of chemicals. One especially promising candidate as platform molecule is 5-hydroxymethylfurfural (5-HMF). Until now 5-HMF was predominantly produced in batch reactions from fructose as substrate within high boiling solvents. A working setup for producing 5-HMF continuously out of fructose or in a coupled two-step reaction, out of glucose, in low boiling solvents is introduced.
