Descrição

Descrição geral

Sodium acetate is an inexpensive and non-toxic chemical substance that is widely used in industry as a food additive or as a base for the neutralization of reaction mixtures.

Aplicação

Sodium acetate can be used as a reagent:

• In the Erlenmeyer-Plochl reaction to synthesize oxazolones by the condensation of aromatic aldehydes and hippuric acid.
• In palladium-catalyzed arylation of thiophenes using aryl halides.

It can also be used as a base to synthesize cinnamic acids via Perkin reaction.
