PROCESS FOR THE ACETYLATION OF WOOD AND ACETYLATED WOOD

A process for acetylation of wood having a density of above 400 kg/m3, particularly, of Southern Yellow Pine, 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 conten...

Beschreibung
Zusammenfassung:	A process for acetylation of wood having a density of above 400 kg/m3, particularly, of Southern Yellow Pine, 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.
