Potassium Acetate
Potassium Acetate (CH₃COOK) is a high-purity carboxylate salt manufactured via the controlled neutralization of industrial-grade acetic acid with potassium hydroxide, followed by multi-stage crystallization and moisture-regulated drying. It is deployed across non-chloride airport runway de-icing, polyurethane foam manufacturing, and food preservation where precise alkali metal stoichiometry and tightly controlled impurity profiles are required.
Our production lines utilize automated reaction tanks and closed-loop evaporation systems operated under ISO 9001 and ISO 22000 guidelines, guaranteeing chemical stability and batch-to-batch consistency.

Applications
Airport Runway & Infrastructure De-icing: Applied as a non-corrosive, chloride-free liquid de-icer meeting AMS 1431 specifications, preventing structural concrete deterioration and protecting airside metal infrastructure.
Polyurethane Foam Catalysis: Functions as an active trimerization and cross-linking catalyst in rigid polyurethane foam production, controlling reaction exotherm and polymer cell structure.
Food Additive (E261): Acts as an efficient buffering agent, preservative, and pH regulator in commercial baking, meat curing, and processed food formulations.
Pharmaceutical Synthesis: Utilized as an alkali metal source and organic synthesis reaction medium for pharmaceutical intermediates and penicillin derivatives.
Product Grades & Options
Solid Crystalline Grade (99% min): Tailored for dry chemical blending, catalytic applications, and organic synthesis.
Liquid Solution (50% - 55%): Formulated using deionized water and passed through sub-micron dual filtration for direct pump injection in airport spray rigs and continuous industrial reactions.
FCC / USP Grade: Complies with Food Chemicals Codex and United States Pharmacopeia monographs for food processing and pharmaceutical manufacturing applications.
Quality Control & Documentation
Production runs are supervised via inline automated titration and digital refractometry. Final batch verification is executed in our certified analytical laboratory using High-Performance Liquid Chromatography (HPLC) for assay determination and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to control heavy metal traces below ppm thresholds.
Standard Compliance Documentation Included with Shipment:
Certificate of Analysis (COA) detailing true batch assay, actual pH, and impurity values.
Safety Data Sheet (SDS) compliant with GHS chemical regulations.
REACH registration documentation (for European shipments) and Kosher/Halal certificates (Food Grade).
Packaging & Storage
Packaging Configurations:
25 kg heavy-duty polyethylene-lined woven bags.
1,000 kg FIBC bulk bags (super sacks) fitted with inner moisture-barrier liners.
200 L sealed plastic drums or 1,200 L IBC totes (for liquid grades).
Storage Guidelines: Store in cool, dry, and well-ventilated storage zones away from concentrated mineral acids and strong oxidizers. Solid potassium acetate is hygroscopic; containers must remain tightly sealed to prevent moisture absorption and caking. Standard shelf life is 24 months from the manufacturing date.
FAQ
Q: Is your liquid potassium acetate fully compliant with AMS 1431 standards?
A: Yes. Our 50% aqueous potassium acetate is manufactured strictly to meet AMS 1431 standards, ensuring controlled biological oxygen demand (BOD) and zero corrosive damage to carbon steel, cadmium, and magnesium aircraft components.
Q: What is the standard lead time for full container load (FCL) orders?
A: Standard production, quality inspection, and export dispatch for FCL quantities take 10 to 14 days from order confirmation. Regional safety stock is maintained near major maritime shipping terminals to support recurring contract schedules.
Q: How do you prevent moisture caking in solid potassium acetate during ocean transit?
A: Solid potassium acetate absorbs ambient moisture easily. We package the material in multi-wall bags featuring an internal polyethylene film heat-sealed under climate-controlled packing lines to prevent humidity ingress.
Q: Do you support customized packaging or private labeling?
A: Yes. We accommodate customer-specified net weights, custom pallet configurations, and neutral or OEM bag printing for qualified industrial distribution partners.
Q: What laboratory equipment is used to verify heavy metal specifications?
A: Trace metallic impurities are measured using ICP-MS (Inductively Coupled Plasma Mass Spectrometry), allowing precise quantification of lead, iron, and other heavy elements down to parts-per-billion levels.
Q: What is the minimum order quantity (MOQ) for industrial grades?
A: The standard MOQ for solid industrial grade is one 20-foot container (18 to 20 metric tons). Laboratory test samples (1 - 5 kg) are readily available upon request for evaluation.
