Potassium Formate (Solid) – Overview
Chemical Formula: HCOOK (or CHKO₂)
Molecular Weight: 84.12 g/mol
Appearance: White crystalline solid or powder
Odor: Odorless
Density: 1.91 g/cm³
Melting Point: ~167–169°C
Solubility:
- Highly soluble in water (~337 g/100 mL at 20°C)
- Slightly soluble in ethanol
- Insoluble in ether
Key Properties
- Hygroscopic: Absorbs moisture from air.
- Alkaline: Aqueous solutions are mildly alkaline (pH ~9–10).
- Reducing Agent: Can act as a mild reducing agent in chemical reactions.
Uses & Applications
- De-icing Agent:
- Used in airport runways and roads (less corrosive than chloride salts).
- Effective at lower temperatures (down to ~−50°C).
- Oil & Gas Drilling Fluid:
- Used in high-density brines for well completion fluids.
- Prevents clay swelling and stabilizes shale formations.
- Chemical Synthesis:
- Intermediate in formic acid production.
- Used in leather tanning and textile processing.
- Animal Feed Additive:
- Sometimes used as a preservative or pH regulator.
Safety & Handling
- Toxicity: Low to moderate (LD₅₀ oral, rat: ~3,300 mg/kg).
- Skin/Eye Contact: May cause mild irritation (rinse with water).
- Ingestion: Non-toxic in small amounts but can cause gastrointestinal discomfort.
- Storage: Keep in a dry, sealed container (hygroscopic).
Regulatory Status
- Generally recognized as safe (GRAS) for specific industrial uses.
- Not classified as hazardous under major chemical regulations (e.g., REACH, OSHA).
Comparison with Other Formates
| Property | Potassium Formate | Sodium Formate |
|---|---|---|
| Solubility | Higher (~337 g/100 mL) | Lower (~97 g/100 mL) |
| Melting Point | ~167°C | ~253°C |
| Density | 1.91 g/cm³ | 1.92 g/cm³ |
| Common Uses | Drilling fluids, de-icing | Leather tanning, dyeing |
Conclusion
Potassium formate is a versatile, water-soluble salt with industrial applications in de-icing, oil drilling, and chemical synthesis. It is less toxic than many alternatives but should still be handled with care due to its hygroscopic nature.
