Dimethylacetamide (DMAc) is a colorless, strong polar aprotic solvent similar to dimethylformamide (DMF). DMAc is stable due to hydrogen bond or dipole-dipole interactions between the external N-H bond and the solvent. Its ions can efficiently interact with hydrogen bonds and liquids that can solvate polar polymers such as cellulose. In this case, the essential factors required for the dissolution of cellulose include:
        i) Solubility of a sufficient amount of electrolyte in the organic liquid;
        ii) Sufficient stability of the electrolyte/solvent complex;
        iii) Cooperative action of the solvated ion-pair on cellulose hydrogen bonds;
        iv) Sufficient basicity of the anion.

DMAc is widely used in synthetic materials, petroleum chemical, reaction catalyst, electrolytic solvent, adhesive industry, as well as a variety of crystalline adduct and complex due to the unique physical and chemical properties. For instance, DMAc is often used as an electrolyte thermally stabilizing additive for lithium ion battery.
