木质素基表面活性剂研究现状

木质素作为一种天然高分子化合物，其来源丰富，可以用来代替石油资源制备表面活性剂，缓解当前石油资源枯竭的问题。常见的木质素基表面活性剂有阳离子表面活性剂、阴离子表面活性剂、两性离子表面活性剂以及非离子表面活性剂。木质素基表面活性剂在工业领域具有广泛的应用范围，可以作为染料分散剂、混凝土减水剂、沥青乳化剂以及原油采集过程中的驱油剂等。木质素基表面活性剂的开发利用为生物质产品的高值化利用开辟了一条新的路径。

Study of Lignin-based Surfactant

Lignin, an abundant nature polymer, can replace petroleum to prepare surfactants and alleviate the shortage of fossil resource. Generally, lignin-based surfactants consist of cationic surfactant, anionic surfactant, amphoteric surfactant and non-ionic surfactant. Lignin-based surfactant has a wide range of applications, such as dye dispersant, water reducer, asphalt emulsifier and oil displacement agent in collection process of crude oil. It gives us a new way to utilize lignin with high add value. The development and utilization of lignin-based surfactants provide a new way for the high value utilization of biomass.
