METHOD FOR PRODUCING THERMOSETTING PHENOLIC RESINS AND PHENOLIC RESINS OBTAINABLE BY THE METHOD

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 carri...

Beschreibung
Zusammenfassung:	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. La invención se relaciona con un método para la producción de resinas termocurables conteniendo la etapa de la transformación de un compuesto fenólico susceptible de policondensación y/o de un formador de aminoplásticos con 5-hidroximetilfurfural (HMF) en condiciones que inducen la formación de productos de policondensación, y se caracteriza porque el HMF comprende al menos un oligómero de HMF. La invención se relaciona además con resinas termocurables y con el uso de las resinas para la producción de una materia compuesta de madera.
