ResumoThe selective synthesis of 5-hydroxymethyl-2-furancarboxaldehyde was carried out using a water-ion-exchanger-extracting solvent, triphasic system as developed earlier using d-fructose as a model substrate. The system was applied to the processing of various hexoses and of plant material extracts. In the case of polyholosides, particularly inulin, the ion-exchange resin catalyses both the hydrolysis of the plant polymer and sugar dehydration. The direct processing of Jerusalem artichoke extracts in the presence of ion-exchangers in the H+ form allowed HMF to be obtained selectively in the extracting solvent.
