Introduction and properties of dimethylacetamide
Dimethylacetamide, the full name is N,N-dimethylacetamide (chemical formula: CH3C(O)N(CH3)2, abbreviated as Dmac or DMA. A commonly used aprotic polar solvent. Colorless transparent liquid, flammable. Can be used with Organic solvents such as water, alcohol, ether, ester, benzene, chloroform and aromatic compounds can be mixed at will. It is used in pharmaceuticals, synthetic resins, and is also used as a solvent for polyacrylonitrile spinning and the extraction of styrene from the carbon eight fraction. Distilled solvents, etc. are produced by the action of diamine and acetyl chloride.
Specific uses of dimethylacetamide
Used as a raw material for synthetic fibers and an excellent polar solvent for organic synthesis; used in organic synthesis and also used 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 to separate styrene from the C8 fraction, and is widely used in polymer films; coatings and medicines, etc. . It is currently widely used in medicine and pesticides to synthesize antibiotics and pesticides.
It can be used as a reaction catalyst; electrolytic solvent; paint remover and a variety of crystalline solvent adducts and complexes.
Used as solvent, paint remover, catalyst and in organic synthesis.
Precautions
1. Many chemicals are dangerous goods, and it is necessary to check whether they are dangerous goods.
2. Shipping regulations: Ensure that there is a 5%-10% gap in the box. In other words, the liquid content must not exceed 90% of the total capacity.
3. Sealing strip: All liquid items need to be sealed twice at the mouth of the container to avoid liquid spillage.
4. Chemicals from some origins are identified as anti-dumping products, and a certificate of origin must be provided for confirmation.
5. Packaging filling requirements: Delivery liquids must use corresponding fillers and adsorbent materials, and the interior should be fully filled to prevent accidents caused by dimethylacetamide shaking in the outer packaging.
6. Dimethylacetamide exported to Argentina can confirm whether it is a dangerous goods through MSDS. There is no dangerous goods category, UN code, and packaging category, that is, ordinary chemicals.
