Aplicaciones

Potassium acetate is used as deicer to remove snow and ice from the surface and considered as a replacement for calcium chloride or magnesium chloride. It is used as a food additive, as a buffer in biological research, as an extinguishing agent used in class K fire extinguishers and as a catalyst to produce polyurethane polymers. It is utilized for the precipitation of dodecyl sulfate bound proteins, thereby removal of proteins from DNA. It plays an important role in preserving tissues, fixation and mummification.

Notas

Hygroscopic. Air and moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.

Has been found to give faster reaction than sodium acetate in the Perkin condensation of carboxylic acid anhydrides with aromatic aldehydes: Org. Synth. Coll., 3, 127, 426 (1955); review: Org. React., 1, 210 (1942).

The nucleophilicity of acetate anion, e.g. in benzene or acetonitrile, is greatly increased in the presence of 18-crown-6: Tetrahedron Lett., 2417 (1974). In a comparative study of various anions in acetonitrile, 'naked' acetate, formed in this manner, was surprisingly found to be the most nucleophilic: Tetrahedron Lett., 4205 (1975).
