Acetic acid dimethylacetamide; N, N-Dimethylacetamide.


DMAC is mainly used as a solvent for synthetic fibers (acrylonitrile) and polyurethane spinning and synthetic polyamide resins, and is also used as an extractive distillation solvent for separating styrene from C8 fractions, and is widely used in polymer films, coatings and pharmaceuticals, etc. aspect. At present, it is widely used in medicine and pesticide to synthesize antibiotics and pesticides. It can also be used as a catalyst for the reaction, an electrolytic solvent, a paint scavenger, and a variety of crystalline solvent adducts and complexes.


N,N-Dimethylacetamide, also known as acetyldimethylamine, acetyldimethylamine, or DMAC for short, is an aprotic highly polar solvent with a slight ammonia odor, strong solubility, and a range of soluble substances. It is widely miscible with water, aromatic compounds, esters, ketones, alcohols, ethers, benzene and chloroform, etc., and can activate compound molecules, so it is widely used as a solvent and catalyst. In terms of solvent, as a solvent with high boiling point, high flash point, high thermal stability and chemical stability, it can be used for polyacrylonitrile spinning solvent, synthetic resin and natural resin, vinyl formate, vinyl pyridine and other copolymers and Aromatic carboxylic acid solvent; in terms of catalyst, it can be used in the process of heating urea to produce cyanuric acid, the reaction of halogenated alkyl and metal cyanide to produce nitrile, the reaction of sodium acetylene and halogenated alkyl to produce alkyl alkyne, and the reaction of organic halide and cyanate to produce isocyanate. N,N-dimethylacetamide can also be used as a solvent for electrolysis solvent and photographic coupler, paint remover, organic synthesis raw material, pesticide and pharmaceutical raw material. Extractive distillation solvent for separating styrene from C8 fraction, etc.
