N,N-Dimethylacetamide is a highly polar aprotic solvent,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.
Product introduction
N,N- dimethylacetamide(DMAc or DMA) is the organic compound with the formula CH3C(O)N(CH3)2. This colorless, water-miscible, high-boiling liquid is commonly used as a polar solvent in organic synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.
