A COMBINED PROCESS OF HYDROLYSIS AND ESTERIFICATION OF WOOD

The invention relates to a method of treating a cellulose-based material, for example wood and engineered wood, wherein the process involves the following steps: - Selecting and placing the cellulose-based material in a treatment chamber; - Impregnating said cellulose-based material with an impregnating agent consisting of an aqueous solution comprising a fluid suitable for esterification; - Facilitating a hydrolysis process whereby the impregnating agent reacts resulting in the formation of esters and polyesters inside the cellulosed-based material.
