| 摘 要： | 以苯酚为液化试剂,在低温和低浓度酸催化剂的条件下对竹粉进行选择性酚化,优化获得热化学高值转化竹材或竹材下脚料的配方与工艺。红外光谱测试结果表明竹粉在热化学酚化条件下发生了降解反应,并产生了具有新取代基的苯环结构的酚化产物。竹粉中的无定形组分(部分纤维素组分、半纤维素组分)和木质素组分完全被酚化,得到了具有很好流动性的高活性酚化液,可用于制备高性能环保型酚醛胶,并获得中试产品。而未被酚化的残渣为高度结晶的竹纤维素,经分离得到高纯度的竹纤维素微粉。同时探讨了竹材分离转化的机理。 |
| 关 键 词： | 竹粉 选择性酚化 竹纤维粉 酚醛胶 |

| Abstract: | With phenol as liquefaction medium,the thermochemical selective liquefaction of bamboo powder is carried out under lower temperature and lower acid-catalyzed concentration,and the optimal formulaion and procedure of the thermochemical phenofication is then obtained.The structural modification of bamboo powder before and after liquefaction via phenol is investigated with FTIR.The results show that the component of bamboo powder is degraded partially and new substitutes are produced during the phenolic proces... |
| Keywords: | bamboo powder selective liquefaction bamboo-fibre powder phenol-formaldehyde adehesive |
