Dioxane lignin prepared from sago palm (Metroxylon sagu) was characterized by analytical pyrolysis coupled to gas chromatography-mass spectrometry. Large abundances of the p-hydroxybenzoates ester-linked to the lignin were proven by analytical pyrolysis as well as by mild alkaline treatment that produced p-hydroxybenzoic acid in 16.3% yield. Pyrolysis in the presence of tetramethylammonium hydroxide (TMAH) before and after alkaline treatment also showed the presence of ester- and ether-linked p… Expand

Thermochemolytic behavior of β–β lignin structures in the presence of tetramethylammonium hydroxide (TMAH)
Abstract Tetramethylammonium hydroxide (TMAH) thermochemolysis is widely used as an effective tool for characterizing hydrolyzable biopolymers such as lignin because it provides more productsExpand
Evaluation of harvesting time effects on kenaf bast lignin by pyrolysis-gas chromatography
A Chinese kenaf (Hibiscus cannabinusL.), variety Sekko-ichi, was planted in May 1996, and harvested at 76, 116, 152, 185, and 226 days after planting. The hand-separated bast fibers were analyzed forExpand
