DMAC is mainly used as a solvent for which materials?

The scientific name of DMAC is Dimethylacetamide, and the molecular formula is CH3CON(CH3)2. Dimethylacetamide can dissolve a variety of compounds, and can be completely miscible with water, ethers, ketones, esters, etc. It has the characteristics of high thermal stability, resistance to hydrolysis, low corrosion, and low toxicity. It has a wide range of uses. Dimethylacetamide has good solubility for various resins, especially polyurethane resins and polyimide resins. It is mainly used as a solvent for heat-resistant synthetic fibers, plastic films, coatings, medicine, and acrylonitrile spinning. At present, it is mostly used to produce polyimide film, soluble polyimide, polyimide-polyperfluoroethylene propylene composite film, polyimide (aluminum) film, soluble polyimide molding powder, etc. abroad; It is mainly used as an excellent polar solvent for polymer synthetic fiber spinning and other organic synthesis.
In organic synthesis, dimethylacetamide is an excellent catalyst, which can accelerate the reactions of cyclization, halogenation, cyanation, alkylation and dehydrogenation, and can increase the yield of main products. In the production of some medicines and pesticides, dimethylacetamide can also be used as a solvent or co-catalyst. Compared with traditional organic solvents, it can improve product quality and yield.
