    摘要: Provided is a method for producing colored wood, the method including: a step of impregnating a block of wood with an organic acid aqueous solution containing an organic acid; and a step of performing steam treatment at high temperature and high pressure on the block of wood in a wet state of being impregnated with the organic acid aqueous solution while keeping the block of wood in the wet state. In the steam treatment, the temperature is 110° C. or more and 160° C. or less and the pressure is a saturated steam pressure at the temperature.

    摘要: The invention relates to a process for acetylation of wood having a density of above 400 kg/m3, particularly, of Southern Yellow Pine, and acetylated wood obtainable by this method. The described acetylation process 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.
