Abstract: A method for producing thermosetting phenolic resins includes the step of reacting a polycondensable phenolic compound with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products. The HMF includes at least one HMF oligomer, and the reaction step is carried out at pH values greater than 7 for more than 60 minutes. Further, thermosetting phenolic resins may be used for producing a wood composite material.

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.

Abstract: Processes for the manufacture of thermally curable resins contain the step of the reaction of a polycondensation-capable phenolic compound and/or of an aminoplastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to formation of polycondensation products. The HMF includes at least one HMF oligomer. Further, thermally curable resins produced by such processes may be used for the manufacture of a wood composite material.

Abstract: A process for the manufacture of wood composite materials includes the steps of: preparation of a thermally curable resin by reacting a polycondensation-capable phenolic compound and/or an amino plastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products, bringing the resin into contact with lignocellulose-containing material, and curing the resin with formation of the wood composite material. The 5-hydroxymethylfurfural includes at least one HMF oligomer. Further, wood composite materials are obtainable by the process.
