Co-salen配合物催化氧化二聚体木素模型物的反应机理
Reaction mechanism of Co-salen complex catalyzed oxidation of dimeric lignin model compound
摘要
Abstract
In order to investigate the Co - salen catalytic bleaching mechanism of pulp, the dimeric guaiacyl lignin model compound with β-O-4 linkage was synthesized. The degradation products and functional groups in Co- salen catalytic oxidation were analysed by GC -MS, FT- IR and 13C -NMR, respectively.The degradation mechanism of lignin model compound was elucidated based on the degradation products and structural changes. Attacks of peroxy anionic radical, hydroperoxy ion and hydroxy radical in Co - salen catalytic system made the β-O-4 linkage broke, ary ring open and methoxy reduced, yielding aldehyde,phenol and alkene.关键词
