【 摘 要 】

References(20)Cited-By(1)In this paper, 1-butylrpridinium bromide was synthesized, in which the solubility and regeneration of garlic stem in [BPy]Br and [BPy]Br /DMSO dissolution system were examined in the temperature range of 100–240°C. The results show that [BPy]Br can efficiently dissolve and degrade stalks, and DMSO can effectively improve the solubility of garlic stem and accelerates the dissolution rate at the optimum ratio of n[Bpy]Br : nDMSO=1 : 8. With the increase of dissolution temperature and time, the solubility of garlic stem in [BPy]Br and [BPy]Br /DMSO increased correspondingly. The regenerated and undissolved cellulose samples in pure ionic liquid and mixed solvent were characterized by FT-IR, XRD, TG-DTG and SEM. It was found that [BPy]Br significantly affected the structure and surface characteristics of the garlic stem. The garlic stem were degraded in the ionic liquid of [BPy]Br effectively, indicating [BPy]Br has good degradation ability to the cellulose.
