General description
Potassium acetate (KOAc) is the potassium salt of acetic acid. It is commonly used as a base in organic synthesis for various reactions, which include Lossen rearrangement of hydroxamic acids, E2 eliminations, deprotonations of alcohols, transition metal-catalyzed reactions, and fragmentation reactions. Additionally, KOAc is also used as a nucleophilic catalyst for addition and polymerization reactions.
Application
Potassium acetate can be used as an activating agent for the activation of carbon materials.
