摘　　要：采用傅立叶红外光谱法分析了竹刨花在苯酚与聚乙二醇-400溶剂作用下酸催化液化产物的化学结构,以及液化物甲醛树脂的结构特征。分析表明:在液化过程中木质素、纤维素和半纤维素都发生了不同程度的降解,产生了很多的小分子物质;并且同时加入两种液化试剂,可以使竹刨花发生两种不同的液化反应。The chemical structure of the liquefied product of bamboo shaving in phenol and PEG-400 solvent catalyzed by acid and the structure of its formaldehyde resin were investigated by FT-IR.The analyses indicated that lignin,cellulose and hemi-cellulose of bamboo were decomposed in different degree by liquefaction.It generated a lot of small molecules.When two liquid reagents were added two different kinds of liquefaction reaction could occur.
