摘　　要：马尾松是我国重要的用材树种,由于其树脂含量过高,通常需要经过脱脂处理后才能投入生产和使用。简要介绍了马尾松松脂的化学成分、物理性质和化学性质,并对其脱脂原理,以及松脂对木材利用的影响进行了阐述。在此基础上,总结了马尾松的脱脂方法,包括物理法中的干燥脱脂法、溶剂萃取法、溶剂汽相法和微波爆破法,以及化学法中的碱液皂化法和酸性脱脂法。最后,对马尾松脱脂研究的趋势和不足进行了探讨,以期为马尾松脱脂技术的迭代进步提供参考。Pinus massoniana Lamb.is an important timber tree species in China.But due to its high resin content,it usually needs to be degreased before it can be put into production and use.In this article,the chemical composition,physical and chemical properties of masson pine resin,as well as the degreasing mechanisms,and the impact of pine resin on its wood utilization were briefly introduced.On this basis,the degreasing methods of Pinus massoniana including physical methods such as dry degreasing,solvent extraction,solvent vapor phase,and microwave explosion,as well as chemical methods,such as alkaline saponification and acidic degreasing were summarized in details.Afterwards,the trends and deficiencies of research on degreasing of Pinus massoniana were discussed,in order to provide reference for future research on the degreasing technology of Pinus massoniana.
