General description
Potassium acetate is a hygroscopic potassium salt. It can be prepared by the neutralization of acetic acid with potassium hydroxide or potassium carbonate. It can be used as nucleophilic catalyst for polymerization and addition reactions, source of acetate anion in substitution and addition reaction. It can be used as a base and promoter in various organic reactions.
Application
Potassium acetate is used as a catalyst:
Potassium acetate is also used as a promoter:
- In the preparation of 2-hexadecylfuran from furfuraldehyde and palmitic anhydride.
- Potassium acetate can be used as a base:,In Lossen rearrangement of hydroxamic acids to carbamic acids.
- In E2 elimination reactions.
- In the formation of lactones from alkoxyamide substrates.
Potassium acetate is also used as a promoter:
- In the borylation of aryl chlorides with bis(pinacolato)diboron in presence of palladium catalyst.
- In the β-boration of α, β-unsaturated ketones.

Potassium glutamate accumulates upon hyper-osmotic shock and serves as a temporary osmoprotectant. This salt leads to transcriptional activation of sets of genes that allow the cell to achieve long-term adaptation to high osmolarity. The current experiments show that potassium glutamate
