Dimensional stability of wood acetylated with acetic anhydride solution of glucose pentaacetate

"Five wood species were acetylated with acetic anhydride (AA) solution of glucose pentaacetate (GPA) at 120 deg C for 8h, and the effect of GPA on the dimensional stability of the acetylated wood was investigated. Some GPA was introduced into the wood cell wall during acetylation. The GPA remai...

Description
Summary:"Five wood species were acetylated with acetic anhydride (AA) solution of glucose pentaacetate (GPA) at 120 deg C for 8h, and the effect of GPA on the dimensional stability of the acetylated wood was investigated. Some GPA was introduced into the wood cell wall during acetylation. The GPA remaining in the cell lumen penetrated the cell wall effectively after heating to more than 140 deg C for lOmin. The bulking effects of GPA resulted in a 10%-30% increase in the anti-swelling efficiency of the acetylated wood with 20% GPA/AA solution in place of AA. Hydrophobic GPA did not deliquesce under highly humid conditions and it remained in the cell wall after boiling in water"
