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.
Claims13
A method for producing thermosetting phenolic resins comprising the step of
- reacting a polycondensable phenolic compound with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products,
- wherein the HMF comprises at least one water-soluble HMF oligomer with 2 to 10 monomer units of 5-hydroxymethylfurfural, and
- wherein the reaction step is carried out at pH values greater than 7 for more than 60 minutes.
