One Step Regioselective Acylation of Polyphenolic Wood Extractive and Its Application for Wood Treatment

This study evaluated the methods of grafting commercial catechin with fatty acids, namely capric acid (C10), lauric (C12), and myristic (C14) through esterification. Specimens beech wood (Fagus sylvatica L.) were impregnated modified catechin-fatty separately, at a 5% concentration diluted in ethanol using vacuum pressure treatment subjected to leaching. The weight percentage gain before leaching (WPG), after (WPGAL), loss due (PL) investigated. Both leached unleached samples tested against white-rot fungi (Trametes versicolor) Petri-dishes for twelve weeks. Results show that treated acids provide improved resistance towards Catechin-C14 was found be more promising, possibly its chain length. decay does not differ significantly between not. Despite antifungal properties catechin, alone insufficient protect from fungi. Further, it is recommended increase level obtain significant effect on resistance.
