• General Description: 1-Butyl-3-methylimidazolium acetate (BMIM Acetate) is an ionic liquid known for its effectiveness as a solvent for cellulose and chitosan dissolution. Its physicochemical properties, such as viscosity and conductivity, are influenced by temperature and van der Waals interactions, with longer alkyl chains in carboxylate anions increasing ion pairing and reducing conductivity. Additionally, it exhibits salting-out effects in aqueous two-phase systems and can dissolve cellulose at ambient temperatures when combined with polar cosolvents. The anion's alkyl chain length also impacts cellulose solubility, with shorter chains generally enhancing dissolution. These properties make it valuable for applications in polymer processing, recycling, and green chemistry.
