Acetylation correctly variations the compounds with absolutely free hydroxyls within Wooden into acetate esters. This is certainly accomplished by reacting the wood with acetic anhydride, which comes from acetic acid.

This treated Wooden makes use of a fireplace retardant chemical That is still steady in large temperature environments. The hearth retardant is applied under pressure in a Wooden treating plant similar to the preservatives explained higher than, or utilized for a surface coating.
