摘要
木质素是自然界中来源丰富的可再生芳香族聚合物,可用于高附加值化学品、生物燃料、建筑材料和高分子材料的制备,但因其结构复杂,直接工业应用有限.通过化学或物理的方法作用于天然木质素结构中的某些活性基团,可改变其特性.改性后的木质素特性优良,在工业上得到了更好的应用.介绍了木质素的结构组成、主要化学改性方法及改性后木质素在表面活性剂、减水剂、树脂材料及香精香料等方面的应用,为木质素的进一步研究提供参考.
Lignin is nature's abundant renewable sources of aromatic polymers, it can be used to produce high value-added chemicals, bio-fuels, building materials and polymer materials. But its direct industrial application is very limited due to its complicated structure. Based on the basic structure of lignin composition briefed, lignin' s chemical modification methods and application of modified lignin in surfactant, water reducer, resin materials, flavors and fragrances and other aspects were introduced, which provided a reference for further study of lignin.
