APPLICATIONS

N,N-Dimethylacetamide (DMAc)
is a clear oily liquid miscible in all proportion with water;
melting point -20 C, boiling point 165 C at 1013 hPa.
It is dissolved in most of organic solvents including
alcohols, ethers, ketones,
chlorinated and aromatic solvents except aliphatic hydrocarbons.
DMAc is produced from acetic acid and dimethylamine. It is the acetic acid amide with two methyl group
substituents on the nitrogen atom. The is formic acid analogue is N,N,-dimethylformamide (DMF).
DMAc is less toxic than DMF. The good water solubility
and excellent solvent power particularly for high molecular
weight polymers and resins make DMAc as a common solvent
in man-made fibre and polyurethane production. DMAc
is also used as a solvent for production of X-ray and
photo-resist stripping compounds. N,N-Dimethylacetamide is a dipolar aprotic solvent with a high boiling
point. DMAc is a good reaction medium and catalyst. It facilitates the SN2
reaction mechanism. It is a reactor solvent or plasticizer for cosmetic and
pharmaceutical intermediates. It is also used as an extraction agent
for gases and oils. |
