Dimethylacetamide, collectively referred to as N,N-dimethylacetamide, abbreviated as DMAC or DMA. One is often used as an aprotic polar solvent. Colorless, transparent liquid, flammable. It can be mixed with organic solvents such as water, alcohol, ether, ester, benzene, chloroform and aromatic compounds. It is used in the manufacture of pharmaceuticals, synthetic resins, as a solvent for the spinning of polyacrylonitrile, and as an extractive distillation solvent for separating styrene from a carbon eight fraction. It is prepared by the action of dimethylamine and acetyl chloride.

Used as a raw material for synthetic fibers and an excellent polar solvent for organic synthesis; used in organic synthesis, also as a solvent, catalyst and paint remover;
DMAC is mainly used as a solvent for synthetic fiber (acrylonitrile) and polyurethane spinning and synthetic polyamide resin. It is also used as an extractive distillation solvent for separating styrene from C8 fraction, and is widely used in polymer film; coating and medicine. . It is currently used in large quantities in medicines and pesticides to synthesize antibiotics and pesticides.
It can be used as a catalyst for the reaction; an electrolytic solvent; a paint scavenger and a plurality of crystalline solvent adducts and complexes. Used as a solvent, paint remover, catalyst and for organic synthesis.
