N,N-dimethylacetamide, also known as acetyl dimethylamine, acetyl dimethylamine, or DMAC for short, is a non-proton, highly polar solvent with a slight ammonia smell. It has a strong solubility and can dissolve a wide range of substances. It can be miscible with water, aromatic compounds, esters, ketones, alcohols, ethers, benzene, and chloroform, and can activate compound molecules. Therefore, it is widely used as a solvent and catalyst. As a solvent with high boiling point, high flash point, high thermal stability, and chemical stability, it can be used as a solvent for polyacrylonitrile spinning, synthetic Chemicalbook resins and natural resins, copolymers such as vinyl formate and vinyl pyridine, and solvents for aromatic carboxylic acids; as a catalyst, it can be used in processes such as heating urea to produce cyanuric acid, reacting alkyl halides with metal cyanides to produce nitrile, reacting sodium acetylene with alkyl halides to produce alkyl acetylenes, and reacting organic halides with cyanates to produce isocyanates. N,N-dimethylacetamide can also be used as an electrolytic solvent and a solvent for photographic colorants, a paint stripper, an organic synthesis raw material, and a pesticide and pharmaceutical raw material. Extractive distillation solvent for separating styrene from C8 fractions, etc.
