SYNTHESIS OF 1-ALLYL,3-METHYLIMIDAZOLIUM-BASED ROOM- TEMPERATURE IONIC LIQUID AND PRELIMINARY STUDY OF ITS DISSOLVING CELLULOSE
characterized and used for dissolving cellulose.The solubility of cellulose in [AMIM] Cl was better than in 1-butyl
3-methylimidazolium ([BMIM]Cl).The pristine cellulose and two cellulose samples regenerated from [AMIM]Cl and [BMIM] Cl solutions were compared by FTIR
WAXD and TGA measurements.Results show that these two RTILs are non-derivatizing solvents for cellulose.After regeneration from RTIL solutions.the crystalline form of cellulose films is completely transformed from cellulose Ⅰ to cellulose Ⅱ.Compared to pristine cellulose
the regenerated cellulose exhibits a lower onset temperature of thermal decomposition
