Description

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:

Oxazolones via Erlenmeyer Plochl condensation reaction of aromatic aldehydes and hippuric acid.
Cinnamic acids via Perkin reaction between aromatic aldehydes and acid anhydrides.

A mixture of sodium acetate-acetic acid buffer can be employed in the polybromination of substituted imidazoles to synthesize polybrominated imidazoles.

It can also be used as a catalyst in tandem Knoevenagel-Michael multicomponent reactions.
