Potassium Formate Powder – Technical Datasheet
1. Basic Properties
- Chemical Formula: HCOOK (or CHKO₂)
- CAS No.: 590-29-4
- Appearance: Fine white crystalline powder
- Odor: Odorless
- Molecular Weight: 84.12 g/mol
- Density: ~1.91 g/cm³
- Melting Point: 167–169°C
- pH (1% solution): ~9–10 (alkaline)
2. Solubility & Hygroscopicity
- Water Solubility: Extremely high (~337 g/100 mL at 20°C)
- Other Solvents:
- Slightly soluble in ethanol
- Insoluble in ether, acetone
- Hygroscopic: Absorbs moisture rapidly—store in airtight containers.
3. Key Applications
✅ De-icing Agent
- Preferred for airport runways (low corrosion, effective down to −50°C).
- Environmentally friendlier than chloride salts.
✅ Oil & Gas Drilling Fluids
- High-density brine for well completion (replaces halides).
- Inhibits clay swelling in shale formations.
✅ Chemical Industry
- Reducing agent in organic synthesis.
- Intermediate for formic acid production.
✅ Other Uses
- Leather tanning, textile dyeing, animal feed additive.
4. Safety & Handling
- Toxicity: Low (LD₅₀ oral, rat: ~3,300 mg/kg).
- Skin/Eye Contact: Mild irritation—rinse with water.
- Ingestion: Low risk but may cause GI discomfort.
- Storage:
- Keep dry (hygroscopic!) in sealed plastic or coated steel drums.
- Avoid contact with strong acids (releases formic acid).
5. Technical Comparison (Powder vs. Solution)
| Property | Potassium Formate Powder | Potassium Formate Solution |
|---|---|---|
| Concentration | ~98–99% purity | Typically 50–75% aqueous |
| Handling | Dust control needed | Easier to pump, less hygroscopic |
| Storage | Requires moisture-proofing | Less sensitive to humidity |
| Primary Use | Industrial synthesis, drilling | De-icing, ready-to-use fluids |
6. Suppliers & Packaging
- Common Forms: 25 kg bags, 500–1000 kg big bags, bulk totes.
- Purity Grades:
- Industrial grade (~95%)
- High-purity (>98%, for chemical synthesis)
Why Choose Potassium Formate Powder?
✔ High solubility – Ideal for concentrated brines.
✔ Low corrosion – Safer for metals/concrete than chlorides.
✔ Eco-friendly – Biodegradable (degrades to potassium + formate).
Need a substitute? Sodium formate (less soluble) or calcium formate (non-hygroscopic) may be alternatives.
