Abstract:
The invention relates to a process for the production of 5-hydroxymethylfurfural from a feedstock comprising at least one sugar using a combination of at least one catalyst selected from the homogeneous Lewis acids, the heterogeneous Lewis acids and the heterogeneous bases and at least one homogeneous Brønsted acid catalyst selected from the families of the thioureas, the sulphonic acids and the phosphorus-containing organic compounds, alone or in a mixture, in the presence of at least one aprotic polar solvent, at a temperature comprised between 30° C. and 300° C., and at a pressure comprised between 0.1 MPa and 10 MPa.

Claim (Index 11):
Process according to  claim 1 , in which said homogeneous Br\u00f8nsted acid catalyst is selected from the family of the sulphonic acids of general formula: in which R 7  is selected from\n the halogen groups, \n the alkyl groups, linear or branched, cyclic or non cyclic, comprise 1 to 20 carbon atoms being able to be substituted or not with at least one substituent selected from:\n the oxo group, \n the halogen groups and, \n the aryl groups, fused or not, being able to be substituted or not with halogen groups and/or linear or branched, cyclic or non cyclic alkyl groups comprising 1 to 20 carbon atoms, \n \n the aryl groups comprising 6 to 14 carbon atoms being able to be substituted or not with at least one substituent selected from:\n the alkyl groups, linear or branched, cyclic or non cyclic, comprising 1 to 20 carbon atoms, being able to be substituted or not with at least one halogenated group or at least one nitro group, \n the halogenated groups and, \n the nitro group.
