1-Allyl-3-methylimidazolium chloride room temperature ionic liquid: A new and powerful nonderivatizing solvent for cellulose
TLDR
In this paper, a new and highly efficient direct solvent, 1-allyl-3methylimidazolium chloride (AMIMCl), has been used for the dissolution and regeneration of cellulose.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.read more

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.
