Brief Introduction:
Potassium acetate (KOAc) is a versatile compound with a wide range of applications. As a potassium salt, it is used as an acidity regulator in the food industry and in the medical field for electrolyte supplementation, restoration of water-electrolyte balance, and as a urine and system alkalizer. In addition, potassium acetate has also shown important applications in materials science, such as as a simple and efficient activator for the synthesis of porous carbon materials containing two-dimensional nanosheets with a large aspect ratio and a flat surface, a thickness of only 5 nanometers, and a specific surface area of up to 1425 square meters per gram, which is suitable for electrode materials for high-performance supercapacitors. During the pyrolysis of biomass, potassium acetate can significantly reduce tar formation, promote the production of combustible gases, and enhance deoxygenation, decarboxylation and demethoxylation reactions by reacting with carboxyl and hydroxyl groups in the substrate, thereby increasing gas production. The potassium remaining in the biochar can also be further used as a slow-release potassium fertilizer, increasing the application value of the solid product. These properties make potassium acetate a compound of great significance in many fields.
Food additives
Potassium acetate is used as a food additive (E261) for preservation and flavoring.
Inorganic compounds
It is an inorganic salt because it is derived from the reaction between an inorganic base (potassium hydroxide) and an organic acid (acetic acid).
Alkaline salts
Potassium acetate can be considered an alkaline salt due to its basic properties when dissolved in water.
Buffering agents
It is commonly used in buffer solutions due to its ability to stabilize pH levels.
