Thermodynamics of cellulose dissolution in an imidazolium acetate ionic liquid

Thermodynamics of cellulose dissolution in an imidazolium acetate ionic liquid.

The heat of dissolution of cellulose in one imidazolium acetate ionic liquid was determined experimentally. The value of -132 ± 8 J g(-1) indicates that the dissolution is exothermal thus confirming energetically favourable cellulose-ionic liquid interactions but indicating that an increase in temperature does not thermodynamically favour the dissolution process.

Facile Cellulose Dissolution and Characterization in the Newly Synthesized 1,3-Diallyl-2-ethylimidazolium Acetate Ionic Liquid

A facile cellulose solvent 1,3-diallyl-2-ethylimidazolium acetate ([AAeim][OAc]) with high electrical conductivity has been designed and synthesized for the first time, via a quaternization reaction and ion exchange method. The dissolution characteristics of cellulose in this solvent were studied in detail. Meanwhile, the co-solvent system was designed by adding an aprotic polar solvent dimethy...

Rapid Dissolution of Cellulose in Ionic Liquid with Different Methods

Simulation of a cellulose fiber in ionic liquid suggests a synergistic approach to dissolution

Ionic liquids dissolve cellulose in a more efficient and environmentally acceptable way than conventional methods in aqueous solution. An understanding of how ionic liquids act on cellulose is essential for improving pretreatment conditions and thus detailed knowledge of the interactions between the cations, anions and cellulose is necessary. Here, to explore ionic liquid effects, we perform al...
