IUPAC name of Acetamide is ethanamide. It is an organic compound. It’s chemical formula is CH3CONH2. It is also known as Acetic acid amide. It is the simplest form of amide and it is derived from acetic acid. It is used as a plasticizer. It has applications in industries also. It is used as an industrial solvent there.DMA is a related compound and is more widely used. It’s preparation is different from acetamide. Acetamide acts as an intermediate between acetone and urea. Acetone consists of two methyl (CH3) groups that are present on both sides of the carbonyl. Urea consists of two amides (NH2) groups. Acetamide is a mineral that occurs naturally.

Methods Of Production


1.Laboratory scale

Acetamide can be formed in a huge amount by doing the ammonolysis of acetylacetone. This process is done under suitable conditions. It is generally used in reductive amination.It can be prepared from anhydrous acetic acid, dried hydrogen chloride gas and acetonitrile . It can be done with the help of an ice bath. Yield obtained is generally low , and the acetamide that is formed in this way is generated as a salt along with HCl.

2.Industrial scale

It is similar to some laboratory methods . Acetamide is obtained by dehydrating ammonium acetate. It can also be obtained by doing the hydration of acetonitrile. Byproduct of the production of acrylonitrile is Acetonitrile.

Safety Hazard Of Acetamide(CH3CONH2)

  • There is low toxicity in acetamide which leads to deduction in weight. When it is exposed to a high oral dose, it takes place.

  • It is also responsible for the mild irritation of the eyes and skin.

  • Fumes or toxic gases are generated by its combustion.

  • Corneal can also be damaged due to this.

  • Oral exposure can result in tumours like lymphoma and liver tumours.
