摘要： 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.

摘要： The invention relates to a novel process for the conversion of a feedstock comprising at least one sugar to 5-hydroxymethylfurfural, in which said feedstock is contacted with one or more catalysts of the family of the homogeneous sulphonic acids in the presence of at least one aprotic polar solvent, used alone or in a mixture, at a temperature comprised between 30° C. and 200° C., and at a pressure comprised between 0.1 MPa and 10 MPa in which said catalysts are selected from the compounds of general formula

摘要： A process for the transformation of a feed of at least one sugar into 5-hydroxymethylfurfural, contacting the feed with one or more organic catalysts in the presence of at least one solvent, said solvent being water or an organic solvent, alone or as a mixture, at a temperature in the range 30° C. to 200° C., and at a pressure in the range 0.1 MPa to 10 MPa, in which said organic catalysts are selected from compounds from the thiourea family with general formula R1NH—C(═S)—NHR2, in which the groups R1 and R2 are aromatic groups optionally having a heteroatom, linear or branched alkyl groups, which may or may not be cyclic, and alkyl groups with at least one heteroatom, which may be linear or branched, which may or may not be cyclic, said groups R1 and R2 possibly being substituted or unsubstituted and which may be identical or different.
