Abstract
Carbon-linked 5-hydroxymethylfurfural (HMF) oligomers contain at least one first HMF unit and one second HMF unit. The first and second HMF units are linked by a carbon-carbon bond with involvement of an aromatically bound carbon atom at position 3 or 4 of the furan ring of the first HMF unit. The HMF oligomers may be used as reactive carbonyl compounds in the manufacture of thermally curable resins on the basis of phenolic compounds and/or aminoplastic forming agents as well as in the manufacture of wood composite products.
Claims10
A carbon-linked hydroxymethylfurfural oligomer comprising a first hydroxymethlfurfural unit and a second hydroxymethylfurfural unit, wherein the first hydroxymethylfurfural unit and the second hydroxymethylfurfural unit are linked by a carbon-carbon bond with involvement of an aromatically bound carbon atom at position 3 or position 4 of a furan ring of the first hydroxymethylfurfural unit.
A process for manufacturing a hydroxymethylfurfural oligomer comprising:
- (a) providing at least one of an aqueous suspension of a cellulose-containing biomass, an aqueous carbohydrate solution of at least one hexose, and an aqueous 5-hydroxymethylfurfural solution;
- and
- (b) treating the aqueous suspension, the aqueous carbohydrate solution, or the aqueous 5-hydroxymethylfurfural solution under hydrothermal conditions.
A process for manufacturing a hydroxymethylfurfural oligomer comprising:
- (a) providing a substantially pure solution of at least one of hydroxymethylfurfural monomers and hydroxymethylfurfural oligomers;
- and
- (b) exposing the solution under normal pressure to conditions that lead to formation of hydroxymethylfurfural oligomers.
