- Product Description
Anhydrous Potassium Acetate (Solid) – Premium Industrial Grade Chemical for Multi-Industry Applications
SHANXI ZHAOYI CHEMICAL CO., LTD. produces acetate chemicals for industry. Purity levels run high. The company opened its doors in 1988. Our plant is standardized and covers 27,000 square meters. Each year we turn out 150,000 tons. Buyers in industry worldwide count on us for a steady chemical supply. One product we sell is Anhydrous Potassium Acetate (Solid) (CAS 127-08-2). It comes as a refined white crystalline powder. Moisture gets taken in at a steady rate, and it dissolves well. This anhydrous grade holds no crystal water. Common hydrated products do. Purity sits above 99%. Industrial de-icing is one use. Another is oilfield drilling. Drug synthesis ranks as a third. Catalytic reactions are another place it works. The product meets ISO, KOSHER, and HALAL certifications. That gives it wide international use. A few problems get solved by the zero-moisture formula. Shale formations may turn unstable. Corrosion can hit equipment and infrastructure. Exact concentration control can be a struggle for labs and plants.

Key Features & Benefits
This productgives steady, strong results across many tough working conditions. It is made for industrial settings with strict standards and low moisture tolerance.
No water gets in the way of sensitive reactions: during formulation or reaction, it adds no moisture impurity. Its fully anhydrous nature explains why. Drug synthesis and polyurethane foam catalysis both need it as the right raw material. Precise and reliable reaction results come from this.
Quick & homogeneous disintegration: The uniform white crystal structure breaks down fast and fully in water. Against similar products, it gives a big lift to overall manufacturing and processing efficiency. It also helps firms build uniform solution systems faster.
Very Low Corrosion & Longer Equipment Life: No chloride goes into this formula. That means the heavy corrosion plain calcium chloride and sodium chloride bring on never shows up. Rigs, aviation gear, and industrial processing hardware keep running 40% to 60% longer. Replacement costs fall. So do repair bills.
Kind to Nature & Fully Compliant: Once the job is done, nothing hazardous stays behind. The reason is simple. This product breaks down with ease and its BOD/COD numbers stay low. Wastewater treatment rules are strict, and so are the rules for aviation de-icing work. It meets both. Companies can then turn out goods that are safe for nature and fine in the eyes of the law.

How It Works
A steady ionic dissociation sits behind many of these jobs. The same goes for the special chemical mechanisms found inside anhydrous potassium acetate (solid). Take pH buffering. Low-temperature deicing works in much the same way. Shale stabilization fits here too. Industrial catalysis is another case.
Accurate pH Buffering: As it dissolves, acetate ions create a stable acid-base balance. The pH of the solution then sits between 4.5 and 5.5. Build pharmaceutical formulas, or study enzymatic reactions, and the pH stays under control. That control is precise and steady.
Effective Low-Temperature Deicing: Hydrogen bonds hold ice crystals together. Potassium ions break that structure down. Water's freezing point then drops. Deicing and anti-freezing performance stays steady even at -26°C. Nothing corrosive forms from chloride compounds as it works.
Oilfield Shale Stabilization: In water-based drilling fluids, a cation exchange reaction makes potassium cations trade places with the sodium ions found in clay formations. Shale hydration and swelling are held back. Wellbore collapse and wall crumbling then stop. Drilling work can go on safely after that.
Professional Catalytic Effect: In polyurethane manufacturing, this additive speeds up the isocyanate trimerization reaction. A business can adjust the concentration of the solution without much trouble. That setting controls how dense the cross-linking becomes. The foam then comes out at the hardness level you need. You do not have to add extra moisture.
Applications
Pharmaceutical Manufacturing: It works as a buffer during drug synthesis, and again when the final products get formulated. pH values in API solutions stay accurate and consistent. Stability holds up too, and so does the qualification rate of the drug products.
Oilfield Services: International chloride-free environmental laws for oilfield work are met by this product. Mud accretion and bit balling both go down. Reactive clay formations stay stable. Water-based drilling mud also runs at its best.
Infrastructure and Aviation De-Icing: It meets SAE AMS 1431 aviation industry rules in full. Runways and bridges are deiced with it all the time. This keeps chloride corrosion from eating into steel and aluminum alloy structures.
Chemical Synthesis: Fine chemical production needs raw materials with very high purity. This product covers that need. It works as a high-purity potassium source and an analytical reagent. You can put it to use in organic synthesis reactions and in catalyst manufacturing.
Heat Transfer Systems: Industrial heat transfer systems get freeze protection they can depend on. A guarantee against corrosion comes with it. Closed-loop heating and cooling equipment stays safe, since the fluid works as a strong corrosion inhibitor.
A business can reach standard discharge and hold output steady with industrial pH regulation. Textile manufacturing, leather tanning, and industrial wastewater treatment all use it to adjust pH and neutralize acids and bases.

Packaging Options
We stock moisture-proof packaging in several options, matched to different procurement volumes and application scenarios. The product's anhydrous performance stays locked in. Moisture absorption and deterioration during transportation and storage are avoided:
25 kg Moisture-Resistant Bags: These bags use multi-layer kraft paper. A polyethylene liner is inside. It keeps moisture out. Lab trials are a common use. So are small test runs and pilot production.
1000 kg Bulk Bags (FIBC): These bags are strong and woven from polypropylene. A moisture barrier coating is added. They are custom-made for large-scale industrial continuous production. That helps keep product quality stable during bulk transport.
Custom Packaging: We support personalized packaging customization according to customers' special storage conditions and automated feeding system requirements to match diversified production needs.
All packages are equipped with desiccant packs and sealed tightly to completely isolate external moisture and maintain the purity and anhydrous characteristics of the product.

Manufacturing Process
We adopt mature and advanced neutralization production technology, using high-purity acetic acid matched with potassium hydroxide or potassium carbonate as raw materials. The reaction process is completed under precise temperature control to ensure full and uniform reaction and reduce impurity generation from the source.
The crude solution goes through multi-stage gradient crystallization. Next comes vacuum low-temperature dehydration. This step removes all crystal water. It does not damage the original acetate molecular structure. Water content stays below 0.5%. The result is qualified anhydrous products.
Fine grinding comes first. The powder then goes through size screening. Out comes a product with particles spread evenly. That is why dissolution and reaction results stay the same every time. Packing is the final step. It takes place in a sealed space filled with nitrogen. This stops the material from pulling in moisture again.
Every production process has continuous quality Anhydrous potassium acetate (solid) monitoring points. All operations run under strict GMP specifications. That way, consistency stays stable from batch to batch.

FAQ
Q: What sets anhydrous potassium acetate apart from the standard kind?
A: A1: No crystal water is present in the anhydrous grade. Purity ends up higher, and moisture sits lower. Moisture then cannot interfere in catalytic reactions, pharmaceutical synthesis, or other precision work. Performance stays steadier because of that.
Q: How should you store the product once it has been opened?
A: A2: Close the package again as soon as you are done. Keep it in a dry warehouse with low humidity. For long storage, put it in a desiccant cabinet. This keeps moisture out and stops air contact from weakening performance.
Q: Can it stand in for sodium acetate across all industrial uses?
A: A3: It does best in shale stabilization and anti-corrosion work. The price per unit is higher, though. Choose the product that fits what you need for corrosion resistance and what your project budget allows.
Q: When you mix a drilling fluid, how much do you add?
A: A4: For most jobs, the amount runs between 8% and 15% by weight. Tell us what your formation activity looks like and what mud density you want to hit. From there we will work out the dosage changes that fit your case.
Q: Can I use this product where it touches food?
A: A5: Yes. Our KOSHER and HALAL certified grades fully meet food-grade standards and can be safely used as buffering agents and pH regulators in food processing within the specified limit range.
