Dissolution and regeneration of cellulose in sugarcane bagasse from ionic liquid [bmim]Cl

1-Butyl-3-methylimidazolium chloride([bmim]Cl)was used to dissolve cellulose in sugarcane bagasse and cellulose regeneration.Influence of temperature,NaOH concentration and time on the dissolution of cellulose in sugarcane bagasse was investigated.The regenerated cellulose from ionic liquid(IL)was characterized using X-ray diffraction,FT-IR spectroscopy and TGA.Results showed that [bmim]Cl is a good solvent for cellulose and at optimal conditions of 80℃ for 90min with 1% NaOH solution for cellulose activation,by which 48% of dissolution rate of cellulose was achieved.It was also observed that [bmim]Cl is a non-detribalizing solvent for cellulose.The regenerated cellulose from IL showed a crystalline form of cellulose II and was less thermally stable than pure cellulose.
