CHEMICAL MODIFICATION OF BEECH WOOD: EFFECT ON THERMAL STABILITY
Bodirlau, Ruxanda - Teaca, Carmen Alice - Spiridon, Iuliana

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Beech sawdust was reacted with phthalic (PA) and maleic (MA) anhydrides for chemical modification. The influence of reaction time and anhydride amount was investigated. IR spectra gave evidence of wood esterification. Thermogravimetric investigation of chemically modified wood indicated a better…
