Analysis of extractive component from hardwood soda pulping black liquor
摘要
Abstract
The composition of extractive from hardwood soda pulping black liquor was examined by using Py-CCMS, F-IR, GPC, and element analyzer. The different spectra indicate that lignin and organic acids exist in black liquor, of which the lignin from black liquor belongs to Guaiacum (G) -Syringa (S) type lignin. The chain of lignin contains a small amount of α-β double bends of carbon and the mass fraction of S-unit is higher than that of G-unit,and their mass fraction ratio is 2.27. The structural formula of lignin is C9H8.8848 O2. 169 6 (OCH3)1. 188 3, the relative molecular mass of C9 unit formula is 189.79, and its average molecular mole mass is 1 163 g/mol, and the extractive contains many organic building blocks, which are the isomers of each other. Besides, the homologues of squalene were also found in lysate.关键词
