Behaviour of lignin-polysaccharide complex of beechwood upon vacuum drying process

, : Behaviour of lignin-polysaccharide complex of beechwood upon vacuum drying process. Drevarsky Vyskum 41(2): 31-40

Steam- and/or NaOH-pretreated beech wood was examined from the view point of structural changes in the lignin-polysaccharide complex during the vacuum drying process. IR spectroscopy was applied for the determination of crystallinity of the cellulose wood component. The lignin fractions were isolated from wood samples by acidolysis in dioxane and characterized by 13C NMR spectroscopy.
