Analysis of extractive from aspen wood of Xiaoxing Anling soda pulping black liquor by acetyl bromine method
摘要
Abstract
Derivation followed by reductive cleavage (DFRC) method was introduced as a new method for lignin structure analysis.It can be used for selective and efficient cleavage ofβ-O-4 ether linkage and α-aryl ether bonds in the composition of extractive from aspen wood soda pulping black liquor.By DFRC method, aspen wood lignin was decomposed, and the composition and structure of extractives from aspen wood soda pulping black liquor were analyzed through GC and GC-MS.The results show that the extractive from aspen wood soda pulping black liquor contains 4 compounds: BHT, carbohydrate, organic acids and lignin units.The lignin from extractive of aspen wood belongs to "GS" -lignin.The chain of lignin contains a small amount of double bonds, and the mass fraction of S-unit is higher than that of G-unit, mass ratio of G/S is 1.78.关键词
