Product Description

Product Description

 

 

N,N-Dimethylformamide is a colorless or slightly yellow liquid with a boiling point of 153°C and a vapor pressure of 380 Pa at 20°C. It is freely soluble in water and soluble in alcohols, acetone and benzene.

   
N,N-Dimethylformamide is used as solvent, catalyst and gas absorbent. React violently with concentrated sulfuric acid, fuming nitric acid and can even explode.

Pure Dimethylformamide is odorless, but industrial grade or modified Dimethylformamide has a fishy smell because it contains impurities of Dimethylamine.

Dimethylformamide is unstable (especially at high temperatures) in the presence of a strong base such as sodium hydroxide or a strong acid such as hydrochloric acid or sulfuric acid, and is hydrolyzed to formic acid and dimethylamine.
