DMAC termékismeret megosztása

N,N-dimethylacetamide, also known as acetyldimethylamine, acetyldimethylamine, orDMAC 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, and can activate compound molecules, so it is widely used as solvents and catalysts.

In terms of solvents, 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 resins and natural resins, vinyl formate, vinyl pyridine and other copolymers and aromatic hydrocarbons Solvent for carboxylic acid; in terms of catalyst, it can be used in processes such as heating urea to produce cyanuric acid, reacting alkyl halides with metal cyanides to produce nitriles, reacting sodium acetylene with alkyl halides to produce alkyne, 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 couplers, a paint remover, an organic synthesis raw material, a pesticide and a pharmaceutical raw material. Extractive distillation solvent for separating styrene from C8 fraction, etc.

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.
