木素化学改性及其在聚氨酯合成中的应用

Research Development of Lignin Chemical Modification and Its Application on the Synthesis of Polyurethane

化学改性可改善木素的性能,拓宽木素的应用范围,提高其利用价值。本文综述了木素在磺化、氧化、胺化、缩合、接枝共聚、烷基化和羟基化反应等化学改性方面的研究进展,并介绍了改性产物在聚氨酯材料合成中的应用,为木素在聚氨酯材料中的高效利用提供参考。

Chemical modification can improve the properties offignin, broaden the application scope oflignin and increase utility value. In this paper, the research progress of lignin chemical modification was discussed, including sulfonation, oxidation, amination, condensation, graft copolymerization, alkylation and hydroxylation reaction. The application of modified products on polyurethane synthesis was introduced in order to provide a reference for the future utilization oflignin in polyurethane materials.
