Resumen

GIRIDHAR, N et al. Dimensional stabilization of wood by chemical modification using isopropenyl acetate. Maderas, Cienc. tecnol. [online]. 2017, vol.19, n.1, pp.15-20. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2017005000002.

Chemical modification of wood with isopropenyl acetate (IPA) using iodine (I2) as catalyst has been carried out. Rubber wood (Hevea brasiliensis) specimens were reacted with IPA using iodine (I2) catalyst at 95°C up to 10 h under solvent free conditions. The effect of catalyst concentration and reaction time was studied. The extent of acetylation was measured by determining weight percent gain and the modified wood was characterized by FTIR-ATR and 13C NMR spectroscopy. It was found that IPA in the presence of iodine is an excellent acylating reagent for wood. Modified wood exhibited high dimensional stability.

Palabras clave : Chemical modification; dimensional stability; iodine; isopropenyl acetate; rubberwood.
