Product Description
N,N-Dimethylacetamide is a highly polar aprotic solvent, micro ammonia odor, very strong dissolving power, soluble wide, miscible with water, aromatics, esters, ketones, alcohols, ether, benzene and chloroform and other arbitrary and enable activation of molecular compounds. It is widely used as a solvent and a catalyst. The solvent, with high boiling point, flash point, thermal stability and chemical stability of the solvent, is used for polyacrylonitrile spinning solvent, synthetic resin and natural resins, formic acid vinyl ester resin, vinyl pyridine copolymer and aromatic carboxylic acid. The catalyst can be used in the process of urea heating to produce the reaction of cyanide, sodium halide and metal cyanide to produce the reaction of alkyl acetylene, organic halide and isocyanate. N,N-dimethylacetamide also can be used as electrolytic solvent and photography with coupler solvent, de paint agent, organic synthesis of raw materials, pesticide and pharmaceutical raw materials. Separation of styrene from C8 fraction, extraction, distillation, solvent, etc.

Uses
N,N-Dimethylacetamide is used as a polar solvent in organic synthesis as well as in reactions involving strong bases such as sodium hydroxide. It is also used as a solvent for fibers like polyacrylonitrile, spandex, as an excipient in drugs viz. vumon, busulfex and in the adhesive industry. It finds application as a reaction medium in the production of pharmaceuticals, agrochemicals, dyes and plasticizers. It is widely used in polymer industry due to its high solving power for high molecular-weight polymers and synthetic resins. It plays an important role as a catalyst in various reactions viz. cyclization, halogenation, cynidation, alkylation and dehydrogenation and increases the yield of main products. It is also used as an extracting agent for oil and gases, in paint removers, in the production of photo-resist stripping compounds and as booster solvent in coatings.
