Properties :

Potassium Acetate is white crystal, fine granule and powder. The Density, Melting Point and Water Solubility of Potassium Acetate is 1.57, 292℃ and 2694g/l (25℃).





Potassium Aacetate can be used in the production of betapen, reagent, anhydrous ethanol, catalyst, auxiliary and filler. Potassium Acetate can be used as a deicer instead of chloride salts such as Calcium Chloride or Magnesium Chloride. Potassium Acetate offers the advantage of being less aggressive on soils and much less corrosive, and for this reason is preferred for airport runways. Potassium Acetate is, however, more expensive. Potassium acetate is also the extinguishing agent used in class K fire extinguishers because of its ability to cool and form a crust over burning oils. In medicine, Potassium Acetate is used as part of replacement protocols in the treatment of diabetic ketoacidosis because of its ability to break down into bicarbonate and help neutralize the acidotic state. Potassium Acetate is used as a food additive as a preservative and acidity regulator. In molecular biology, Potassium Acetate is used to precipitate dodecyl sulfate (DS) and DS-bound proteins, allowing the removal of proteins from DNA. Potassium Acetate is also used as a salt for the ethanol precipitation of DNA. Potassium acetate is used in mixtures applied for tissue preservation, fixation, and mummification. Most museums today use the Formaldehyde-based method recommended by Kaiserling in 1897 which contains Potassium Acetate.



Potassium Acetate is packed in 25KG plastic lined woven bag.
