Abstract
The invention relates to a process for manufacturing 5-hydroxymethylfurfural consisting of bringing a hexose into contact with a catalytic support in the form of a solution of said hexose in a strongly polar aprotic solvent, particularly dimethylsulfoxide, the 5-hydroxymethylfurfural formed being extracted by means of a solvent for the latter also brought into contact with the catalytic support. All of the operations are carried out preferably continuously, particularly by the counter-current principle.
