摘要： 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.

摘要： The present invention describes a process for the acetylation of wood comprising treating wood with an acetylation agent comprising acetic anhydride and/or acetic acid and subjecting to acetylation conditions, wherein the acetylation reaction is carried out in the presence of an acetylation catalyst comprising a salt of an organic acid, wherein the organic acid is a carboxylic acid, phenol or a substituted phenol, wherein the carboxylic acid is chosen from the list consisting of aromatic carboxylic acids, medium chain saturated monocarboxylic acids, keto acids, dicarboxylic acids, tricarboxylic acids, hydroxy acids, amino acids and derivatives thereof.
