说明

一般描述

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.
 

应用

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.
