How do I get rid of dimethylacetamide?
Distillation will be one option if your compound is liquid and stable and if your compound is already precipitated then just simple washing with low boiling solvents and keep that solid in low boiling solvents for exchange to remove completely.
What is DMAC used for?
DMAC is a dipolar aprotic solvent used for many organic reactions and industrial applications. It is a versatile solvent due to its high boiling point and good thermal and chemical stability. DMAC is applied as solvent in wet spinning processes for the production of acrylic fibres.
Is dimethylacetamide harmful?
Toxicity. Dimethylacetamide, like most simple alkyl amides, is of low acute toxicity. Chronic exposure can cause hepatotoxicity. At high doses (400 mg/kg body mass daily), dimethylacetamide causes effects on the central nervous system (e.g. depression, hallucinations and delusion).
Is dimethylacetamide flammable?
* Dimethyl Acetamide is a COMBUSTIBLE LIQUID. * Use dry chemical, CO2, or alcohol or polymer foam extinguishers.
How do you remove dichloromethane from a reaction mixture?
DMF usually removed completely by dissolving the product in distilled water and stirring the solution for an hour then separate the solid product by filtration, If the product oily separates it by extraction with ethyl acetate. Better to dissolve your product in non-polar solvent if it dissolves.
What is the boiling point of N N dimethylacetamide?
165 °C

Is dimethylacetamide volatile?
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….Dimethylacetamide.

How is dimethylacetamide used in the chemical industry?
Synthesis, reactions, applications. Dimethylacetamide is commonly used as a solvent for fibers (e.g., polyacrylonitrile, spandex) or in the adhesive industry. It is also employed in the production of pharmaceuticals and plasticizers as a reaction medium. It is an important Lewis base used to establish the ECW model .
How is dimethylamine acetic acid ( DMA ) prepared?
DMA is obtained with 99% yield referred to methyl acetate. 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:
Is the odor of dimethylacetamide the same as ammonia?
DIMETHYLACETAMIDE; is a clear colorless liquid with a faint odor similar to ammonia;. About the same density as water;. Flash point 145°F. Vapors heavier than air. May by toxic by skin absorption. May irritate eyes and skin. Clear, colorless liquid with a weak, ammonia-like odor. Odor threshold concentration is 46.8 ppmv (Leonardos et al., 1969).
How is dimethylacetamide harmful to the unborn child?
Dimethylacetamide is a medium potency reproductive toxicant ( toxic for reproduction, category 1B) and may damage fertility or the unborn child. It is harmful in contact with skin or if inhaled and causes serious eye irritation. Dimethylacetamide can cause hepatotoxicity, including occupational dimethylacetamide exposure-induced hepatotoxicity.
