Abstract: A new and highly efficient direct solvent, 1-allyl-3-methylimidazolium chloride (AMIMCl), has been used for the dissolution and regeneration of cellulose. The cellulose samples without any pretreatment were readily dissolved in AMIMCl. The regenerated cellulose materials prepared by coagulation in water exhibited a good mechanical property. Because of its thermostable and nonvolatile nature, AMIMCl was easily recycled. Therefore, a novel and nonpolluting process for the manufacture of regenerated cellulose materials using AMIMCl has been developed in this work.

Improved classical united-atom force field for imidazolium-based ionic liquids: tetrafluoroborate, hexafluorophosphate, methylsulfate, trifluoromethylsulfonate, acetate, trifluoroacetate, and bis(trifluoromethylsulfonyl)amide.
TL;DR: The proposed force field gives a good description of the self-diffusion coefficients and shear viscosities, which is comparable to the recently developed polarizable force field.

TL;DR: A series of hydrophilic and hydrophobic 1-alkyl-3-methylimidazolium room temperature ionic liquids (RTILs) have been prepared and characterized to determine how water content, density, viscosity, surface tension, melting point, and thermal stability are affected by changes in alkyl chain length and anion.

Characterizing ionic liquids on the basis of multiple solvation interactions.
TL;DR: A linear free energy approach is used to characterize 17 RTILs on the basis of their distinct multiple solvation interactions with probe solute molecules and provides data that can be used to help identify the interactions and properties that are important for specific chemical applications.

TL;DR: Hydrophilic ionic liquids can be salted-out and concentrated from aqueous solution upon addition of kosmotropic salts forming aqueously biphasic systems as illustrated by the phase behavior of mixtures of 1-butyl-3-methylimidazolium chloride and K3PO4.

Unconventional methods in cellulose functionalization
TL;DR: In this paper, a review of synthesis pathways for the preparation of unconventional cellulose derivatives with alternative functional groups and patterns of functionalization is given. But the authors focus on the application of NMR spectroscopy including two-dimensional methods and of chromatographic techniques after specific sample pretreatment as enzymatic and acidic partial or complete depolymerization.
