Method for producing products based on wood as a raw material

Abstract

A method is disclosed for producing products based on wood as a raw material. The method includes wood, in the form of wood particles, being subjected to an extraction treatment using an extracting agent. The extracting agent may include one or more organic solvents in an organic-aqueous mixture of the solvent or solvents with water. A content of fatty acids in the wood particles is reduced, by the extraction treatment of the wood particles using the solvent, by at least 70%, measured as hexanal content in wt. % after accelerated aging for 72 h at 90° C., while the content of cellulose, hemicelluloses and lignin is largely maintained during this extraction treatment.
