PROCESS FOR THE PREPARATION OF 5-HYDROXYMETHYL FURFURAL BY HETEROGENEOUS CATALYSIS

PROCESS FOR THE PREPARATION OF 5-HYDROXYMETHYL FURFURAL BY HETEROGENEOUS CATALYSIS

A method for preparing 5-hydroxymethyl furfural by contact catalysis, wherein a liquid medium containing at least one hexose, e.g. fructose, is contacted with a solid catalyst consisting of a tectosilicate or clay which is not functionalized by acid groups, e.g. a zeolite in proton form such as an H...

Zusammenfassung:A method for preparing 5-hydroxymethyl furfural by contact catalysis, wherein a liquid medium containing at least one hexose, e.g. fructose, is contacted with a solid catalyst consisting of a tectosilicate or clay which is not functionalized by acid groups, e.g. a zeolite in proton form such as an H mordenite. The HMF thereby formed can be extracted using an organic solvent such as methylisobutylketone in a counter current extraction apparatus.
