Title (EN) PROCESS FOR THE ACETYLATION OF WOOD AND ACETYLATED WOOD
(FR) PROCÉDÉ D'ACÉTYLATION DE BOIS ET BOIS ACÉTYLÉ
Abstract: front page image
(EN)The invention relates to a process for acetylation of wood having a density of above 400 kg/m3, particularly, of Southern Yellow Pine, and acetylated wood obtainable by this method. The described acetylation process allows the production of acetylated wood having higher acetylation levels, such as an acetyl content of at least 20% by weight. The acetylated wood has also a low residual acetic acid content, in particular, lower than 1% by weight. The invention is particularly useful for acetylation on industrial scale of pieces of solid wood, preferably, of wood beams.
(FR)L'invention concerne un procédé d'acétylation de bois ayant une densité supérieure à 400 kg/m3, en particulier le pin des marais, et le bois acétylé pouvant être obtenu par ce procédé. Le procédé d'acétylation de l'invention permet à la production de bois acétylé d'avoir des niveaux d'acétylation plus élevés, telle qu'une teneur en acétyle d'au moins 20 % en poids. Le bois acétylé présente également une faible teneur en acide acétique résiduel, en particulier, inférieure à 1 % en poids. L'invention est particulièrement utile pour l'acétylation à l'échelle industrielle de pièces de bois massif, de préférence, de poutres en bois.
