Abstract: Disclosed is a process for the acetylation of wood, wherein the wood is impregnated with acetylation fluid and heated in stages. It is thereby secured that an acetylation reaction is conducted at a temperature above the boiling temperature of the acetylation fluid, at a stage where the impregnated wood is largely devoid of free acetylation fluid (i.e., acetylation fluid not retained in the wood matrix or in capillaries). Preferably, the process is conducted in a plant having conveyors, such as transportation screws, in the zones in which the separate heating steps are conducted.

Abstract translation: 公开了一种木材乙酰化方法，其中木材用乙酰化液浸渍并分阶段加热。 由此确保乙酰化反​​应在乙酰化流体的沸点温度以上的温度下进行，在浸渍木材大部分没有游离乙酰化流体的阶段（即乙酰化流体未保留在木质基质或毛细血管中 ）。 优选地，该方法在具有输送机例如输送螺杆的工厂中进行单独加热步骤的区域中进行。
