La presente se dirige a un proceso de acetilación continua de elementos de madera. El proceso combina particularmente un paso de impregnación discontinua con un paso de reacción continua. A objeto de realizar lo anterior, se incorpora un paso de recogida, de modo que los lotes de elementos de madera impregnados son introducidos en un reactor de una manera continua. Puede obtenerse un contenido de acetilación sumamente alto de un nivel no logrado anteriormente en los procesos de acetilación continuos y no catalizados. The invention is directed to a process for the continuous acetylation of wood elements. The process particularly combines a batchwise impregnation step, with a continuous reaction step. In order to realize this, a collection step is built-in, so as to allow batches of impregnated wood elements to be fed into a reactor in a continuous manner. Very high acetylation contents can be obtained, at a level that had not been achievable before in a continuous and non-catalyzed acetylation process.
