探讨麦草纤维素在离子液体溴代N-乙基吡啶[EPy]Br中的溶解性能,并采用红外光谱等手段对麦草纤维素在离子液体中溶解和再生前后的结构变化进行分析。结果表明,未经活化的麦草纤维素可溶解于离子液体而不发生其他衍生化反应。并探讨离子液体的回收。
The solubility of wheat straw cellulose in ionic liquid brominated N-ethylpyridine [EPy] Br was investigated. The structure changes of wheat straw cellulose in ionic liquid before and after the dissolution were analyzed by infrared spectroscopy. The results showed that unbleached wheat straw cellulose soluble in the ionic liquid without other derivatization reactions. And to explore the ionic liquid recovery.
