Lipids from Flax Fibers and Their Fate in Alkaline Pulping

摘要: The chemical composition of lipids from bast fibers flax (Linum usitatissimum), which are commonly used for high-quality paper pulp production, was thoroughly studied by gas chromatography-mass spectrometry. main compounds identified were waxes, series long chain n-fatty alcohols, n-aldehydes, acids, and n-alkanes. Free esterified sterols triterpenols, steroid hydrocarbons, triterpenoid ketones, as well sterol glycosides also found in the fibers. On other hand, fate these lipophilic alkaline pulping investigated analyzing two pulps obtained under distinct industrial cooking conditions. results revealed that while waxes could be efficiently hydrolyzed during depending on alkali charge, most present survived unbleached pulps.
