Potassium Formate Liquid (Aqueous Solution) – Technical Overview
1. Basic Properties
- Chemical Formula: HCOOK (aqueous solution)
- CAS No.: 590-29-4
- Appearance: Clear, colorless to slightly yellowish liquid
- Odor: Odorless or mild formic acid-like smell
- Density: Varies with concentration (typically 1.35–1.57 g/cm³ at 25°C)
- pH: ~9–11 (alkaline)
- Freezing Point: Depends on concentration (e.g., −50°C for ~75% solution)
2. Common Concentrations & Specifications
| Concentration | Density (g/cm³) | Freezing Point | Typical Use |
|---|---|---|---|
| 50% solution | ~1.35 | ~−35°C | De-icing, drilling fluids |
| 75% solution | ~1.57 | ~−50°C | High-density brine, oilfield applications |
Purity: Industrial grade (≥95% HCOOK) or high-purity (≥98%).
3. Key Applications
✅ Oil & Gas Industry
- High-density drilling/completion fluid (replaces CaCl₂, ZnBr₂).
- Shale stabilizer – Reduces clay swelling better than chlorides.
✅ De-icing & Anti-icing
- Airport runways, roads – Non-corrosive, biodegradable.
- Effective down to −50°C (better than urea or glycols).
✅ Industrial Uses
- Heat transfer fluid (high thermal stability).
- Leather tanning, textile dyeing (pH regulator).
✅ Chemical Synthesis
- Reducing agent in organic reactions.
- Formic acid precursor.
4. Advantages Over Solid Form
✔ Ready-to-use – No dissolution required.
✔ Lower dust risk – Safer handling than powder.
✔ Pumpable – Easier for industrial applications.
5. Safety & Handling
- Toxicity: Low (LD₅₀ oral, rat: >2,000 mg/kg).
- Skin/Eye Contact: Mild irritation – rinse with water.
- Storage:
- Keep in HDPE or stainless steel tanks (resists corrosion).
- Avoid contact with strong acids (releases formic acid).
- Environmental Impact:
- Biodegradable (breaks into K⁺ + formate).
- Less toxic to aquatic life than chlorides.
6. Comparison with Other De-icers
| Property | Potassium Formate | Sodium Formate | Calcium Chloride |
|---|---|---|---|
| Freezing Point | −50°C (75%) | −20°C (saturated) | −51°C (30%) |
| Corrosivity | Low | Low | Moderate |
| Eco-Friendliness | High | High | Low (chloride pollution) |
| Cost | Higher | Moderate | Low |
7. Suppliers & Packaging
- Common Packaging:
- IBC totes (1,000 L), drums (200 L), bulk tankers.
- Leading Suppliers:
- Perstorp, BASF, ADDCON, Taminco.
8. Regulatory Status
- Generally Recognized as Safe (GRAS) for industrial uses.
- Not classified as hazardous under OSHA/REACH.
- EU Approved for airport de-icing (EC No. 1272/2008).
Conclusion
Potassium formate liquid is a high-performance, eco-friendly fluid for oilfield, de-icing, and chemical applications. Its low corrosion, ultra-low freezing point, and biodegradability make it superior to traditional salts.
