Dissolution and Regeneration of Reed Leaf Fibers in Imidazole-Based Ionic Liquids

Abstract:

In this paper, regeneration of reed leaf fibers that have been degummed pretreatment in high temperature and pressure dissolved in 1-butyl-3-methylimidazolium chloride ionic liquids was studied. The samples containing 5% or 10%(wt/wt)reed leaf fibers in the ionic liquids, at 90°C for 7h.The dissolution process was viewed by polarizing microscope. Fourier-transform infrared spectroscopy(FT-IR) and X-ray diffraction were used to visualize the crystalline of reed leaf fiber transformed completely from cellulose I to cellulose Ⅱ after regenerated directly from 1-butyl-3-methylimidazolium chloride solution.
