Abstract: 

Beech wood after drying and milling was reacted with alkylatig and acetylating agents. Untreated beech wood meal was reacted with benzyl chloride in the presence of sodium hydroxide. Also beech wood meal in another experiment was pulped with ethylene glycol as pulping liquor for removing lignin and the delignified beech wood was reacted with benzyl chloride in the presence of NaOH. Untreated wood and delignified wood after benzylation show thermal flowability as determined by thermal mechanical analysis (TMA). The benzylation products of untreated and delignified wood were acetylated with acetic acid and acetic anhydride mixture. The thermal flowability of acetylation products were measured by TMA analysis. 1H NMR and FTIR spectra of products were also recorded.
