使用光学显微镜对制备得到的木质素及改性木质素化学结构进行分析。木质素购自TCI公司,取四氢呋喃、木质素以及一定量的HDI加入配有氮气保护的三口烧瓶中,搅拌,室温下自然风干,再烘干,得到改性木质素。
The chemical structure of the lignin and the modified lignin were analyzed by optical microscope.The lignin was purchased from TCI Company. Tetrahydrofuran, lignin and a certain amount of HDI were added into a three-way flask with nitrogen protection, stirred, air-dried at room temperature, and then dried to obtain modified lignin.
