Title:
METHOD FOR TREATING LIGNOCELLULOSIC MATERIALS, IN PARTICULAR WOOD AND MATERIAL OBTAINED BY SAID METHOD
Document Type and Number:
WIPO Patent Application WO2003084723
Kind Code:
A3
Abstract:
The invention concerns a method for chemical treatment of lignocellulosic materials, in particular at least a piece of timber, characterized in that it consists in subjecting said materials to impregnation with a chemical agent comprising hydrocarbon chains, said agent being selected among mixed anhydrides, excluding acetic/benzoic acid mixed anhydride, said agent being adapted to ensure covalent bonding of a plurality of hydrocarbon chains on said materials.
