Die Verbesserung des Schwind- und Quellverhaltens und der Dauerhaftigkeit von Holz mittels Behandlung mit unkatalysiertem Essigsäureanhydrid

Forschung und Praxis


Buchenholz (Fagus sylvatica) wurde mit unkatalysiertem Essigsäureanhydrid behandelt und einige physikalische und biologische Parameter des behandelten mit denen unbehandelten Holzes verglichen. Die radiale und tangentiale Quellung und Schwindung sowie die Aufnahmefähigkeit und Aufnahmegeschwindigkeit des Holzes gegenüber Wasser und Wasserdampf wird durch die Acetylierung stark reduziert, die Dauerhaftigkeit des Holzes gegenüber Pilzen verbessert. Die Ergebnisse werden mit denen anderer Autoren verglichen.

The improvement of dimensional stability and durability of wood through treatment with non-catalysed acetic-acid anhydrid


Beechwood (Fagus sylvatica) was treated with non-catalysed acetic-acid anhydrid and some physical and biological properties of the treated wood were compared with those of non-treated wood. The radial and tangential shirnkage resp. swelling and the absorption capacity of the acetylated wood against moisture is considerably lower. The durability against fungi improves. The results are discussed in comparison to the results of other authors.
