Abstract :In this study, it was aimed to see the superior properties of acetylation technology which protects the wood against to wood destroying organisms perfectly, on particleboards. Therefore,  particleboards made from 1 and 3 hour acetylated particles and gave approximately 15% and 20% weight percent gain, exposed to brown rot fungi  Coniophora puteana according to procedures defined in EN 113 standard.  Biological resistance of acetylated and untreated (control) boards were compared. The acetylated boards demonstrated increased durability against brown rot fungi.  specially 3 hour acetic anhydride treatment reduced the weight losses more significantly than others and showed greater biological resistance.
