AmimCl离子液体对梧桐屑的溶解再生性能
Dissolution and regeneration of Chinese parasol sawdust in ionic liquid 1-ally-3-methylimidazolium chloride
摘要
Abstract
Dissolution and regeneration of Chinese parasol sawdust in 1-ally-3-methylimidazolium chloride (AmimCl) were studied. Observation from a hot stage polarizing microscope demonstrated the dissolution process of Chinese parasol sawdust sample in AmimCl. The dissolution ratio increased with the increase of time and temperature, and the decrease of initial concentration. The highest value of dissolution ratio could reach 23%. The chemical structure of the original and regenerated Chinese parasol sawdust was analyzed by 13C CP/MAS NMR, FT-IR, XRD, TGA-DSC and SEM. The ionic liquid could partially dissolve Chinese parasol sawdust by destructing the inter- and intra-molecular hydrogen bond among lignocelluloses, and the regenerated Chinese parasol with homogenous and dense structure could be obtained. After regeneration, AmimCl could be easily recycled and reused.关键词
