Compositional analysis of the mixture from the reaction of wheat stalk powder in subcritical methanol
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 9
Abstract
Depolymerization of wheat stalk (WS) powder in methanol was investigated. Liquid mixture from the reaction at 220 ℃ was analyzed with gas chromatography/mass spectrometry. In total, 37 compounds were identified, including 11 non-aromatic ones and 26 aromatic-ring containing ones, among which many benzene-ring containing compounds (BRCCs) are products from lignin depolymerization. The mechanisms for depolymerization of lignin in WS are examined according to structures of the BRCCs.
