Specification
Dimethylacetamide, full name N, n-dimethylacetamide (formula: CH3C(O)N(CH3)2 abbreviated DMAC or DMA. A polar solvent commonly used as an aprotic solvent. A clear liquid. 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.
