- Product Description
Dry Sodium Acetate – Industrial Grade Anhydrous Acetate for Multi-Industry Chemical Solutions
Production at SHANXI ZHAOYI CHEMICAL started in 1988. The plant sits on 27,000 ㎡. Each year we turn out 150,000 tons, and that figure has not moved. Industrial buyers worldwide come to us for high-purity Dry sodium acetate (CAS 127-09-3). This white crystalline powder adjusts pH in industrial settings. Pharmaceutical intermediate processing is a second use. Synthesis jobs where moisture causes problems also fit. Purity never falls below 99%. At all times moisture stays under 0.5%. Dissolving the anhydrous grade takes no time at all. Textile auxiliary mills get steadier results from it. The same holds for labs doing buffer work. Trihydrate grades behave differently. Pre-hydration has to happen first. Our sales land in Europe and America. Asia is the other market we cover. From one batch to the next, quality stays the same. The products carry ISO, KOSHER, and HALAL certification.
Key Features & Benefits
This product holds no crystal water. Its active ingredients run 22% higher than conventional trihydrate sodium acetate does. A plant buying in bulk can dose less. Freight and storage costs drop too. That matters when a partnership runs for years. The material is slightly hygroscopic by nature, so ordinary moisture-proof storage is enough. Complete dissolving takes only seconds. Synthesis and intermediate output get faster because of this. Reaction systems hold steady through textile dyeing and pharmaceutical excipient production, since the solution is weakly alkaline (pH 8.0–9.5). Impurity control stays tight on our side. General food-contact standards are met that way. Several industries can put it to use.

How It Works
Add water and this product splits into sodium ions and acetate ions. A buffering system forms that way. It holds the pH of the solution in place and lasts a long time. In textile manufacturing, the material neutralizes acid left over from cloth preparation. Dye then attaches more evenly. Color fastness improves as well. Unwanted hydrolysis does not happen, so precision chemical synthesis gains from the anhydrous form. Delicate intermediates are protected from breaking down that way. Microbes take up high-purity acetate fast, because it works as a carbon source. That is the other role it plays. Denitrification efficiency in industrial wastewater treatment then rises above what conventional trihydrate products can reach.
Applications
Chemical Manufacturing: A reliable base material for building acetate derivatives. Many other organic synthesis routes also put it to good use.
Textile Industry: It works as a pH adjuster you can rely on. With it, dyeing holds steady. Colors also fix more evenly.
Pharmaceutical Production: Here you get a buffering excipient. Moisture levels in it stay low. Drug formulation stays precise when you use it.
Laboratory Use: This reagent is highly pure. Buffer preparation is one task it handles. Routine analysis is another.
Water Treatment: Running costs stay down with this carbon source. For biological denitrification and nitrogen removal, bacteria get exactly what they need.
Adhesive Production: The catalyst holds steady. Formulas where water content matters can use it.

Certifications & Compliance
Every batch we make follows GMP rules. Our certificates are kept up to date too. That covers ISO, KOSHER and HALAL. Because we hold them, we meet the Dry sodium acetate entry rules for markets all over the world. Outside auditors turn up on a set schedule. We let them in every time. Each order also ships with an official batch CoA report. Customs clearance gets easier with it, and it helps you pass quality inspection.
Packaging Options
Moisture stays out with the standard pack. Inside a sealed 25kg bag sits a PE inner liner. Bulk orders ship in 500kg and 1000kg FIBC jumbo bags. Should a client want custom packaging or labels, we can set that up. Pallets get built the proper way, then wrapped so damp air stays away. That way goods survive long sea routes without damage.
Manufacturing Process
Everything starts with neutralization, and we keep that step under tight control. Qualified anhydrous sodium acetate comes out of it. Evaporation runs in several stages. Vacuum dehydration follows. From there, the material goes through centrifugal separation, then drying at low humidity. Milling and screening come next. That is how particle size stays uniform. Each batch passes three rounds of in-process quality testing. Quality holds steady that way, right up to delivery.
Why Choose Us
Acetate production has been our main focus for over 30 years. That history lets us hold a stable 150,000-ton annual output. Long-term bulk orders are fully supported by it. MOQ stays flexible, for trial orders and formal orders alike. Grades can be customized. Delivery moves fast worldwide. Our technical team also gives practical guidance on applications, and after-sales support stays steady.
FAQ
Q: What sets anhydrous sodium acetate apart from the trihydrate form?
A: A1: Moisture in our this product stays below 0.5%. Active content comes in at 99% or higher. It also dissolves fast. Water-sensitive processes can use it for that reason. About 40% crystal water is held in the trihydrate form. Less usable material is left as a result. That also means fewer places where it fits.
Q: How should I store this product?
A: A2: Keep every package closed tight. A dry warehouse is the right place to store it. Air has to move well there. High heat should stay far away. Strong acids and oxidizing substances must not come near it either. Moisture stays out this way. Caking is stopped as well.
Q: Can I use this item near food?
A: A3: The regular industrial grade is not okay for food. If you need one that is, we can send a food-grade material instead. All the certification papers come with it.
Q: What is your minimum order quantity?
A: A4: Our MOQ rules stay flexible. Small trial orders are fine. So are full container bulk shipments. That way each client gets what fits.
Q: Can your team give me professional technical support?
A: A5: Yes. Our technical team works with you one-on-one. You get dosage references. We check if your formula is compatible. When we visit your site, we also advise on process optimization.
