n,n-Dimethylacetamide Cas No. 127-19-5 Dmac 99.9% Purity Pharmaceutical Intermediates
Identification
Dimethylacetamide, fully known as N,N-dimethylacetamide (chemical formula: CH3C(O)N(CH3)2 is abbreviated as DMAC or DMA. One is often used as an aprotic polar solvent. Transparent liquid, flammable, 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 polyacrylonitrile spinning and from carbon. The eighth fraction separates the extraction distillation solvent of styrene, etc. It is obtained by the action of dimethylamine and acetyl chloride.

Application of n,n-Dimethylacetamide Cas No. 127-19-5
- As a solvent with high boiling point, high flash point, high thermal stability and chemical stability, it can be used as a spinning solvent for polyacrylonitrile, synthetic resin and natural resin, copolymer of vinyl formate, vinyl pyridine and aromatic hydrocarbons.
- The solvent of the carboxylic acid; in the catalyst, it can be used for the process of reacting urea to produce cyanuric acid, reacting halogenated alkane with metal cyanide to produce nitrile, reacting sodium acetylide with halogenated alkane to produce alkyl alkyne, reacting organic halide with cyanate to produce isocyanate.
- N,N-dimethylacetamide can also be used as a solvent, a paint remover, an organic synthetic raw material, a pesticide, and a pharmaceutical raw material for an electrolytic solvent and a photographic coupler.
