Product Introduction:
Potassium Acetate, Also known as potassium acetate, it is an important organic salt compound with the chemical formula CH3 COOK. It usually exists in the form of colorless or white crystalline powder, with a weak acetic acid odor, non-toxic and easily soluble in water, ethanol, and glycerol, slightly soluble in ether, and insoluble in acetone. The aqueous solution of Potassium Acetate is weakly alkaline due to the hydrolysis of acetate ions (CH3 COO ⁻) in water.
The preparation method of Potassium Acetate mainly includes acid-base neutralization reaction between acetic acid and potassium hydroxide or potassium carbonate. For example, acetic acid reacts with potassium carbonate to produce Potassium Acetate, carbon dioxide, and water. The reaction equation is:
2CH ∝ COOH+K ₂ CO ∝ → 2CH ∝ COOK+CO ₂+H ₂ O. In addition, Potassium Acetate can also be prepared by reacting acetic anhydride with potassium hydroxide.
Its acid-base indicator color change pH range is between 7-9, specifically 98.2 g/l solution at 25°C. In addition, the pKa value of Potassium Acetate is 4.756, indicating that it is a weak acid.
In terms of stability, Potassium Acetate is hygroscopic, but it needs to be stored away from moisture, heating, fire, self-igniting objects and strong oxidants. It is incompatible with strong oxidants and may react. Its LogP value is -3.72, which is consistent with its high solubility in water.

Potassium Acetate has important applications in chemical industry, food, medicine, agriculture and environmental protection. In the chemical industry, Potassium Acetate is an important raw material for the preparation of other organic compounds, such as the synthesis of ester compounds in esterification reactions, or as an intermediate for metal acetate in the preparation of catalysts and electrobaths.
Potassium Acetate is widely utilized as an acidity regulator and preservative in meat products, baked goods, and seasonings. Not only does it inhibit microbial growth but it also works synergistically with other ingredients to create optimal taste and texture stability in foods. Potassium Acetate optimizes yeast activity by altering pH values in fermentation broths to increase alcohol yield as well as flavor substance content.
Potassium Acetate is widely utilized as an important raw material and excipient in drug synthesis and formulation production, serving both as an intermediate reactant or catalyst; in injection and oral formulations it provides a buffering action which stabilizes pH value of drug as well as increasing shelf life; additionally it may be used as a diuretic to treat diseases related to edema through regulation of electrolyte balance within the body.
In the field of agriculture, Potassium Acetate as a fertilizer synergist can improve the efficiency of nutrient absorption by crops, demonstrating its potential in sustainable agriculture. With the development of agricultural technology, research on the application of Potassium Acetate in functional fertilizer is also deepening to adapt to the development needs of precision agriculture and green agriculture.
In the field of environmental protection, Potassium Acetate is used in water treatment to remove heavy metal ions, and its chelating ability can effectively reduce the toxicity of wastewater. In the battery manufacturing industry, as an electrolyte additive, Potassium Acetate extends battery cycle life by optimizing ion conductivity. Its biodegradability also conforms to the development trend of green chemistry, demonstrating potential in soil remediation and ecological engineering.
The core competitiveness of Potassium Acetate is firstly reflected in its excellent solubility and chemical compatibility. Its solubility in water is as high as 2694 g/L (25 ° C), far exceeding most inorganic potassium salts, which enables it to quickly form homogeneous solutions and is suitable for high-concentration preparations and precision chemical reactions. Meanwhile, the good mutual solubility of Potassium Acetate with organic solvent expands its application scenarios in non-aqueous systems, such as as a phase transfer catalyst in organic synthesis.
Environmental friendliness is another notable advantage of Potassium Acetate. As a biodegradable substance, its residue risk in the environment is extremely low, and it is especially suitable for ecologically sensitive agriculture and food fields. Compared with Potassium chloride, Potassium Acetate does not contain chloride ion, avoiding soil salinization and groundwater pollution caused by long-term use, and meeting the development needs of sustainable agriculture. In addition, by-products from its preparation, such as carbon dioxide, can be recovered through a recycling process, further reducing the carbon footprint.
Its versatility makes Potassium Acetate an ideal choice for cross-industry applications. The same product can be used as a carrier of pharmaceutical sustained-release preparations and as a core component of textile auxiliaries, which reduces the raw material management cost of enterprises. In the field of industrial catalysis, the weak alkalinity of Potassium Acetate can accelerate the esterification reaction without causing strong corrosion problem, which takes into account both efficiency and equipment safety.
Thermal stability and storage stability ensured the industrial application of Potassium Acetate. The decomposition temperature is up to 292℃, which is suitable for high temperature sterilization and melting process. Although hygroscopic property needs to be controlled, it can maintain long-term physical and chemical stability and reduce storage losses through moisture-proof packaging and desiccant assistance.
In terms of economy, although the unit cost of Potassium Acetate is slightly higher than that of traditional potassium salt, its high purity (pharmaceutical grade ≥99%) and low dosage have comprehensive cost advantages in the high-end field. For example, in the production of electronic grade chemicals, a small amount of high purity Potassium Acetate can meet the process requirements and avoid additional expenses for subsequent purification steps.
Synergies are particularly prominent in hybrid applications. For example, in organic acid Potassium liquid fertilizer, the quick efficiency of Potassium Acetate is complementary to the slow release of fatty acid potassium, which not only meets the nutrient requirements of crops at the initial growth stage, but also achieves long-term potassium supply, increasing the fertilizer utilization rate by more than 30%. This collaborative model is extending to more areas of composite materials, leading to the development of new functional products.
