The Effect of Heat Treatment on the Chemical Composition ...

treatment on the chemical composition of wood was studied. The extractives content initially increased up to 200 ºC and 3 h. However, with extended treatment duration it decreased. Hemicellulosic monosaccharide (D-xylose) degraded under all treatment conditions and resulted in a decrease of holocellulose content.
