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.

Method for treating lignocellulosic materials, in particular wood and material obtained by this method

A process for the monomethylation of nitrogenous heterocycles having at least one nitrogen atom bonded to a hydrogen atom by reacting the nitrogenous heterocycle with dimethyl carbonate at a temperature of between 100&#xb0; and 200&#xb0; C. and a pressure of between 0.93&#xd7;10Pa and 1.07&#xd7;10Pa while methanol produced during the reaction is distilled off as it is formed.

The invention relates to a process for the synthesis of aryl alkyl monoethers by reaction of a phenol compound, comprising one or more hydroxyl groups attached to the aromatic system, and of a dialkyl carbonate. It is a solvent-free process carried out at a pressure of between 0.93&times;10 Pa and 1.07&times;10 Pa, at a temperature of between 100&deg; C. and 200&deg; C., and in the presence of a catalyst chosen from the group consisting of alkaline carbonates and alkaline hydroxides. The dialkyl carbonate is added gradually to the reaction mixture.
