  • Wood treated by impregnation with mixed anhydrides
    Patent number: 8034462
    Abstract: Process for the chemical treatment of lignocellulose materials, in particular of at least one piece of wood, characterized in that said materials are subjected to impregnation by a chemical agent comprising hydrocarbonaceous chains, this agent being chosen from mixed anhydrides, except for the mixed anhydride of acetic/benzoic acid, said agent being suitable for providing covalent grafting of a plurality of hydrocarbonaceous chains to said materials.
    Type: Grant

  • USE OF A MATERIAL RESISTANT TO THE DEVELOPMENT OF MICROORGANISMS
    Publication number: 20100215863
    Abstract: Use of a material based on lignocellulose materials, in particular a piece of wood or sawdust, subjected to a process of chemical treatment of said lignocellulose materials, consisting in subjecting said materials to a treatment with a chemical agent comprising hydrocarbon-based chains, this agent being chosen from mixed carboxylic anhydrides, said agent being suitable for ensuring grafting by covalent bonding of a plurality of hydrocarbon-based chains onto said materials, as a material which reduces or even prevents the development of microorganisms, such as fungi or molds, capable of degrading said lignocellulose materials.
