Dissolution performance of cellulose in [A₂im][MOA]/MIM solvents.

ABSTRACT: Cellulose solvents ([A₂im][MOA]/MIM) were developed by combining diallylimidazolium methoxyacetate ([A₂im][MOA]) with N-methylimidazole (MIM). The cellulose solubilities in the ([A₂im][MOA]/MIM) solvents were determined at 25 °C, and the effect of the MIM/[A₂im][MOA] molar ratio on cellulose solubility was systematically investigated. Attractively, the solvents show cellulose solubility as high as 25.2 g 100 g^-1 even at 25 °C. It is proposed that the H2, H4 and H6 in [A₂im]⁺ and the carboxyl O atom in [MOA]^- primarily contribute to the dissolution of cellulose; MIM mainly acts to dissociate [A₂im][MOA] into [A₂im]⁺ and [MOA]^-, and stabilize the dissolve
