    N,N-Dimethylacetamide (DMAc) is widely used to compose the solvent mixtures for cellulose. Static and dynamic light scattering studies of the cellulose dissolved in varying concentrations of DMAc/LiCl mixtures have been reported.

    Application

    N,N-Dimethylacetamide (DMAc) has been employed as an organic solvent for the liquid-phase exfoliation of pristine graphene from bulk graphite.
    Itmay be used to compose the solvent system along with lithium chloride (LiCl) for the dissolution of commercial rayon grade cellulose. DMAc/LiCl solvent mixtures have been used for the preparation of chitin, cellulose and polyimide fibers and films.
    N,N-Dimethylacetamide may be used in the preparation of α-lithio N,N-dimethylacetamide. DMAc along with palladium chloride forms an efficient catalytic system for the oxidation of several internal olefins to carbonyl compounds without undergoing isomerization.
