Potassium Formate丨CAS 590-29-4

Potassium formate丨CAS 590-29-4 (HCOOK) is the potassium salt of formic acid. It appears as a colorless to white crystalline solid that is highly water-soluble. Known for its low toxicity, high solubility, and thermal stability, potassium formate is used in several industrial and environmental applications, particularly where eco-friendly alternatives to traditional salts are preferred.

1. De-icing and Anti-icing Agent
● Runway and roadway de-icer: Potassium formate is widely used for airport runways and road surfaces, as it is less corrosive than traditional salts (e.g., sodium chloride) and is more environmentally benign.
● Aircraft-safe: Its low corrosivity makes it suitable for use in aviation environments, where protection of metal components is critical.
2. Oil and Gas Industry
● Drilling and completion fluids: In high-pressure, high-temperature (HPHT) oil and gas wells, potassium formate brine is used as a weighting agent in wellbore fluids due to its density and stability.
● Environmentally friendly: Its biodegradability and low environmental impact make it preferable over traditional halide salts.
3. Heat Transfer Fluids
● Secondary refrigerants: In cooling systems, potassium formate solutions are used as heat transfer fluids, especially in industrial refrigeration systems and ice rinks, due to their thermal efficiency and low environmental impact.
4. Industrial and Laboratory Use
● Reducing agent: It serves in some organic synthesis and metal finishing processes.
● Preservative and buffering agent: In niche biochemical and chemical processing applications, potassium formate can act as a buffer or stabilizer.
5. Agriculture
● Fertilizer additive: Occasionally used to improve nutrient uptake in specialized formulations, although not as common as other potassium salts.

1. Eco-Friendly De-icing Alternative
Potassium formate丨CAS 590-29-4 is readily biodegradable, causes less soil and vegetation damage, and is safer for surface water and groundwater compared to chloride-based salts.
2. Low Corrosivity
Unlike traditional de-icing agents, potassium formate is significantly less corrosive to concrete, steel, and vehicle parts, making it ideal for infrastructure longevity.
3. High Thermal and Chemical Stability
Its stability under pressure and temperature extremes enhances its value in well operations and cooling systems.
4. Non-Hazardous and Low Toxicity
Potassium formate exhibits low mammalian and aquatic toxicity, supporting its use in sensitive environments, such as airports, urban roads, and agricultural zones.
