Swelling of acetylated wood I. Swelling in organic liquids

Abstract: To investigate the affinity of acetylated wood for organic liquids, Yezo spruce wood specimens were acetylated with acetic anhydride, and their swelling in various liquids were compared to those of untreated specimens. The acetylated wood was rapidly and remarkably swollen in aprotic organic liquids such as benzene and toluene in which the untreated wood was swollen only slightly and/or very slowly. On the other hand, the swelling of wood in water, ethylene glycol and alcohols remained unchanged or decreased b… Show more

“…this promoting effect could be attributed to the swelling of plant tissue by water molecules. Water, in fact, is an effective swelling-inducing agent, due to its small molar volume and high hydrogen bonding capability (11). Swelling makes the tomato paste matrix less compact, favouring the diffusion of the extracting solvent.…”

“…Such an effect is probably due to an on-average higher affinity of the phenolic compounds for ethanol than for water. Nevertheless, other mechanisms such as solvent-induced swelling of the solid matrix may also be involved (Obataya and Gril, 2005;Lavecchia and Zuorro, 2008).…”

“…abilities (26,(28)(29)(30), reversing the analyte absorption in cellulose/hemicellulose tracheid walls does not appear to be a critical factor. The observed specific effect of acetone may be due to the disruption of the hydrogen-bonded aqueous network surrounding the analyte binding sites.…”
