Vagdevi Agrociencias iodine rubberwood isopropenyl acetate Chemical modification dimensional stability 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. 2017 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48549610002 en http://www.redalyc.org/revista.oa?id=485 Maderas.
