General description
Sodium acetate is a hydrophilic organic compound that can be prepared by treating acetic acid with sodium carbonate or sodium hydroxide. It acts as neutralizing agent, catalyst, food additive, and buffer to maintain a specific pH.
Application
Sodium acetate can be used as a base to synthesize:
It can also be used as a catalyst in tandem Knoevenagel-Michael multicomponent reactions.
- Oxazolones via Erlenmeyer Plochl condensation reaction of aromatic aldehydes and hippuric acid.
- Cinnamic acids via Perkin reaction between aromatic aldehydes and acid anhydrides.
It can also be used as a catalyst in tandem Knoevenagel-Michael multicomponent reactions.
