Dissolution of cornstalk in 1-butyl-3-methylimidazolium chloride (BmimCl) and 1-ethyl-3-methylimidazolium acetate (EmimOAc) was studied. Chemical structure and crystalline form of cornstalk before and after dissolution were analyzed by means of FT-IR, TGA, SEM, and XRD. The results show that the crystallinity and thermostability of the regenerated cellulose-rich material slightly decreased after dissolution. Cornstalk directly dissolved in ionic liquids, and no derivatization reaction occurred.
Key words： cornstalk; ionic liquid; dissolution; regeneration
