摘要
对二氧六环木素及β-O-4型邻醌木素模型物与过氧化氢的反应进行了初步研究。结果表明,二氧六环木素与过氧化氢反应后的降解产物中羰基明显增多,而且生成了醌型物质。二聚体β-O-4型邻醌木素模型物与过氧化氢反应的降解产物要比二氧六环木素与过氧化氢反应的降解产物简单得多,是较为理想的研究高得率浆木素邻醌发色基团与过氧化氢反应机理的简单模型化合物。
The reaction of dioxane lignin and β-O-4 type lignin ortho-quinone model compound with hydrogen peroxide was tentatively studied in this paper. The results showed that carbonyl groups in degradation products obviously increased and quinoid matters were produced when dioxane lignin reacted with hydrogen peroxide. The degradation products in the reaction of β-O-4 type lignin ortho-quinone model compound with hydrogen peroxide were much simpler than that of dioxane lignin.β-O-4 type lignin ortho-quinone model compound was a comparatively simple model compound for studying the reaction mechanism of ortho-quinone type lignin chromophore in high yield pulp with hydrogen peroxide.
