Abstract

Abstract: The enzymatic hydrolysis-mild acidolysis lignin (EAL) of wheat straw was isolated through a novel lignin preparation procedure, which has good presentation of the native lignin in fibre wall. Contents of functional groups and arylglycerol-β-arylether bonds, linkage types and dibenzodioxocins (DBDO) structures of EAL were studied intensively through elementary analysis, quantitative ³¹PNMR and method of derivatization followed by reductive cleavage (DFRC).

Key words: wheat straw, lignin, ³¹P NMR, enzymatic hydrolysis-mild acidolysis lignin
