Potassium acetate

White, deliquescent granular powder of potassium acetate (CH3COOK) supplied for industrial and laboratory use. Supplied material is highly water‑soluble and typically forms slightly alkaline aqueous solutions (typical pH range 7.5–9.0), making it less corrosive than many halide or strongly acidic/basic salts.

Key chemical data

• CAS: 127-08-2
• Molecular formula: C2H3KO2
• Molar mass: 98.14 g·mol−1
• Physical form: white, hygroscopic/granular crystalline powder
• Melting point: 288–296 °C
• Solubility: readily soluble in water and miscible with many polar solvents

Performance and handling notes

• Deliquescent: product will absorb moisture from air — store in airtight, moisture‑resistant containers in a cool, dry place.
• Produces mildly alkaline solutions and is typically non‑caustic at working concentrations, which supports substitution for more corrosive salts in many applications.

Typical industrial applications

• Molecular biology: nucleic acid precipitation and laboratory reagent
• Oil & gas: drilling fluid additive
• Glass and polymer production: manufacture and as a catalyst (e.g., in terephthalic acid production for PET, carbon black, polyurethane foams)
• Wood processing: catalyst for acetylation of wood
• Pulp & textile: softening and conditioning agents for paper and textiles
• Agriculture: precursor for potassium‑carbon foliar fertilizers
• Deicing & fire protection: liquid deicer and fire suppressant formulations (ease of application vs rock salt)
• Preservation & formulation: tissue fixation/preservation, antimicrobial preservative, antioxidant, buffer
• Chemical intermediates: reagent/intermediate for lubricants, agrochemicals and laboratory chemicals
• Drying/electrolyte technologies: desiccant and “water‑in‑salt” electrolytes for advanced supercapacitors and aqueous batteries
