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. See more DMA is prepared commercially by the reaction of dimethylamine with acetic anhydride or acetic acid. Dehydration of the salt of dimethylamine and acetic acid also furnishes this compound: CH3CO2H·HN(CH3)2 … See more The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. Hydrolysis of the acyl-N bond occurs in the presence of acids: CH3CON(CH3)2 + … See more Dimethylacetamide, like most simple alkyl amides, is of low acute toxicity. Chronic exposure can cause hepatotoxicity.

WebDMAc is an excellent solvent with high solving power for high molecular-weight polymers and synthetic resins. DMAc is used as a reaction solvent for the manufacture of acryl and polyamide fibres. DMAc is also used for … Webk = 6.9 × 10−8 mol·mol−1·monomer day−1, which means a degree of the molecular weight (Mn) of 47 g·mol−1 per day. However, today, cellulose solutions in DMAc/LiCl at room temperature or below are considered stable. When using DMAc/LiCl without heating the sample, it can be assumed that this is a non-degrading solvent system [19–21].
