A renewable chemical industry must be based on biomass as the only abundant carbon source. The acid-catalyzed dehydration of hexoses (e.g. glucose, fructose or their polymers) yields 5-hydroxymethylfurfural (HMF).

HMF is an intermediate that potentially can be converted into a range of value-added chemicals applicable as, for example, solvents, polymer monomers and fuel additives by catalytic isomerization, oxidation or hydrogenation.

In this context an important future direction is to develop integrated technologies which facilitate multistep catalytic synthesis and combined reactions without intermediate recovery steps.

Such methods may increase space-time-yield and reduce operational costs through minimized expenditure of supplementary chemicals and energy.

This presentation will highlight results obtained in catalytic conversion of hexoses to furanic chemicals in ionic liquids with integrated process technologies combining bio- and chemo-catalysis and modes of operation.
