Uses and applications

What the substance is used for, by industry and function

Solvent, molten acetamide is an excellent solvent for many organic and inorganic compounds. Solubilizer, renders sparingly soluble substances more soluble in water by mere addition or by fusion. Plasticizer, stabilizer. Manufacture of methylamine, denaturing alcohol. In organic synthesis.

Organic synthesis (reactant, solvent, peroxide stabilizer), general solvent, lacquers, explosives, soldering flux, hygroscopic agent, wetting agent, penetrating agent.

It suppresses acid buildup in printing inks, lacquers, explosives, and perfumes. It is a mild moisturizer and is used as a softener for leather, textiles, paper, and certain plastics. ... Acetamide and substituted acetamide-containing thiourea can be used for treatment of herpes viruses. Derivatives can also be used as feeding behavior modifiers.

Acetamide is used as a solvent, plasticizer, and a wetting and penetrating agent.

Functional uses

  • Flavouring and nutrient

How it is made

Prepared by fractional distillation of ammonium acetate.

Interaction of ethyl acetate and ammonium hydroxide.

Acetamide can be produced by several methods. Ammonia reacts vigorously with acetyl halides or acetic anhydride to produce acetamide. Alkyl acetates also react with ammonia to yield acetamide. Dehydration of ammonium acetate is the standard procedure for preparation of acetamide. Finally, acetonitrile is hydrolyzed to yield acetamide in the presence of an acid or base catalyst.
