99.9% Dimethyl acetamide
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.

Application
1)Good polar solvents used as raw materials for synthetic fibers and organic synthesis
2)Organic synthesis, also used as solvent, catalyst and paint remover
3)The use of DMAC is mainly used as synthetic fiber (acrylonitrile) and polyurethane spinning and synthetic polyamide resin is used for solvent, extractive distillation solvent separation styrene from C8 fraction, and is widely used in polymer films,coatings etc..
4)Use for the synthesis of reactive solvents, synthetic fiber spinning and synthetic resin solvent, solvent, paint, etc..
Catalyzer.
