Product Detail

Dimethylacetamide, full name N, n-dimethylacetamide, abbreviated DMAC or DMA. A polar solvent commonly used as an aprotic solvent. Colorless transparent liquid, flammable. It can be mixed with organic solvents such as water, alcohol, ether, ester, benzene, trichloromethane and aromatic compounds. It is also used as a solvent for spinning polyacrylonitrile and an extractive distillation solvent for separating styrene from C-8 fractions. It is prepared by the action of dimethylamine with acetyl chloride.
