Dimethylacetamide, the full name is N,N-dimethylacetamide (chemical formula: CH3C(O)N(CH3)2 abbreviated as DMAC or DMA. A commonly used aprotic polar solvent. Colorless Transparent liquid, flammable. Can be freely mixed with organic solvents such as water, alcohol, ether, ester, benzene, and aromatic compounds. Used in the preparation of drugs, synthetic resins, and also used as a solvent for polyacrylonitrile spinning and carbon Extractive distillation solvent for the separation of styrene in eight fractions, etc.
Dimethylformamide appears as a water-white liquid with a faint fishy odor having chemical formula HCON(CH3)2. It is widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents.
