Description

Description

Dimethylacetamide, collectively referred to as N,N-dimethylacetamide, abbreviated as DMAC or DMA. One is often used as an aprotic polar solvent. Colorless, transparent liquid, flammable. It can be mixed with organic solvents such as water, alcohol, ether, ester, benzene, chloroform and aromatic compounds. It is used in the manufacture of pharmaceuticals, synthetic resins, as a solvent for the spinning of polyacrylonitrile, and as an extractive distillation solvent for separating styrene from a carbon eight fraction. It is prepared by the action of dimethylamine and acetyl chloride.
