Abstract: 
In this study, the decay resistance of acetylated Iranian beech was investigated against the white rot fungus Tramets versicolor. Iranian beech (Fagus orientalis), which is a nondurable wood was modified with acetic anhydride at different temperatures, concentrations and times without using any catalyst. Aceylattion of beech was determined by calculating volume change (Ve) and weight percentage gain (WPG) after solvent extraction using acetone. Different WPGs were obtained at ditTcrent conditions. VC increased linearly with increasing WPG. The decay resistance of the acetylated wood was studied according to ASTM D1413 standard against Tramel. versicolor.
Weight loss (WL) due to decay was reduced significantly when WPG increased. A WPG of 17% was found to be the threshold level of the acetylated wood.
