Abstract
Acetoacetylated wood meal (AAWM) was prepared and a preliminary evaluation of its antifungal activity was carried out. Acetoacetylation of wood meal proceeded almost quantitatively with diketene under optimal reaction conditions, even as a heterogeneous reaction. Diketene concentration was the most important governing factor for this reaction. AAWM with a high weight percentage gain inhibited the fungal growth of Fomitopsis palustris.
