N, N - dimethyl acetamide, also known as acetyl dimethylamine and dimethylamine, referred to as "10-channel DMAC, is a kind of high aprotic polar solvent, a slight ammonia odor, dissolved force is very strong, a wide range of soluble substances, the can with water, aromatic compounds, esters, ketones, alcohols, ether, chloroform and benzene arbitrary miscibility, and can make compound molecular activation, and therefore is widely used as a solvent and catalyst.
In solvent as a high boiling point, high flash point, high thermal stability, chemical stability of solvent, can be used for polyacrylonitrile spinning solvent, synthetic resin, natural resin, formic acid, vinyl acetate, vinyl pyridine copolymer and aromatic carboxylic acid solvent;
In the aspect of catalyst can be used for urea heated cyanuric acid, halogenated reaction with metal cyanide sodium cyanide, acetylene and alkyl halogenated reaction system of acetylene, organic halide reaction with cyanate isocyanate, etc process.
N, n-dimethyl acetamide can also be used as an electrolytic solvent and photochromant solvent, depaint, organic synthetic raw materials, pesticide and pharmaceutical raw materials.
Extraction and distillation of styrene extracted from C8 distillate.
