Abstract
The present invention's modifying method for wood elements includes a step for soaking wood elements in one or a mixture of acetic anhydride, acetic acid, or chloroacetic acid; and a step for acetylating the impregnated wood elements in a gaseous phase. This method makes it possible to reduce the time required for the step of acetylating the wood elements, simplifies the process, reduces fabrication costs, and enables fabrication of a wood fiberboard having high dimensional stability.
