Résumé

Color changes of wood during natural aging and during heat treatment were elucidated to determine whether they could be explained as the result of a mild thermal oxidation process at ambient temperatures. The results of kinetic analysis employing the time-temperature superposition method showed that the color changes during natural aging were mainly the result of an oxidation process. Color changes of heat-treated cellulose were also compared with that of wood and indicated that cellulose is responsible for the color changes of wood during natural aging and during heat treatment.
