Wood Timber Treatment: Acetylation Process

Acetylated wood timber is rapid growth wood (generally the cheapest wood available), which has been treated to have better dimensional stability, durability, UV resistance and paint retention. Application The treatment technology is based on the acetylation process. Acetic anhydride (CH3CO)2O is used as a reagent for this process.

Vaisala K-PATENTS® Process Refractometer PR-43-GC is installed in the reactor feed to measure and maintain the correct concentration of acetic anhydride in acetic acid. The second installation point is in the recycling plant’s distillation columns, where the spent chemical is recycled into the process. The refractometer assists in reducing the operating costs of distillation units via real-time process control and optimization.
