Structure and Thermal Stability of Sugarcane Bagasse Cellulose Regenerated from Dialkylphosphate Ionic Liquids
A phosphate-based ionic liquid,1-ethyl-3-methylimidazolium diethylphosphate (”EMIM””DEP”),was synthesized and used to dissolve sugarcane bagasse cellulose under microwave radiation.The original and regenerated cellulose were both characterized by X-ray diffraction,infrared spectroscopy,thermogravimetric analysis and scanning electron microscopy.The results showed that cellulose had a more porous and less crystalline structure after regeneration,whereas chemical composition had no change.Thermal stability of the regenerated cellulose was somewhat lower,corresponding to the decreased crystallinity.In short,the treatment with ”EMIM””DEP” led to desirable structural modification on sugarcane bagasse cellulose via physical process.This is of great benefit to the subsequent downstream processes,such as enzymatic hydrolysis and ethanol fermentation.
