Decay resistance of acetic, propionic and butyric anhydrides modified rubberwood against white rot (Trametes versicolor)

The effectiveness of rubberwood modified with acetic, propionic and butyric anhydrides against white rot Trametes versicolor was investigated. Specimens measuring 5 mm × 20 mm × 20 mm (l × w × t) underwent a Soxhlet extraction with toluene/methanol/acetone (4:1:1 by volume) for 8 h, and then oven-dr...
