- Product Description
High-Purity Industrial Sodium Acetate Trihydrate for Precision Chemical Applications | Reliable quality with Strict Impurity Control
SHANXI ZHAOYI CHEMICAL CO., LTD makes industrial acetate products. Quality standards at the plant are strict. Effective content in our High-Purity Industrial Sodium Acetate Trihydrate is 58-60%, and it holds at that level. Chloride impurity is very low: ≤0.03%. We have made the product in-house since 1988. That is more than 35 years of experience. The production factory is standardized and covers 27,000 ㎡. Output reaches 150,000 tons a year, which keeps bulk supply steady. This industrial-grade crystalline salt (CAS NO.: 6131-90-4) gives steady, reliable performance in precision textile dyeing. Electroplating processing is another use. So is chemical synthesis. Industrial pH buffer systems also depend on it. Other complex industrial settings use it as well. High-precision industrial production brings hard quality demands. We meet those demands.

Key Features & Benefits
Ourthis product keeps its place in the industrial market for one reason. Impurity control covers the whole process. Chloride remains under 0.03% and is controlled tightly. Because of that, impurity interference stays out. Compatibility with sensitive and precision industrial processes remains high.
Mild alkalinity in this product stays stable. pH buffering also works well. Adjustment needs across several industrial production links are handled with flexibility. Inside the system, acid-base balance remains steady. Water solubility is high too. The product dissolves fast in water. Crystallization causes no trouble, and neither does precipitation. On-site solution preparation gets much simpler, and so do operation procedures.
It gives strong value for the money. Wastewater treatment projects use it as a low-cost carbon source supplement that works well. Running costs for companies go down as a result. The crystals flow freely. They also resist caking during long storage. Handling them each day is easy. Moving and storing them are simple too. Product activity stays steady for the whole service cycle.

How It Works
Bound water molecules sit fixed inside a stable trihydrate molecule. That structure gives the lasting buffer effect. Consistency holds in aqueous solutions. pH swings from molecular structural changes do not happen.
High-Purity Industrial Sodium Acetate Trihydrate dissolves in water and then releases acetate ions slowly and evenly. These active ions fine-tune the pH of the solution. Plenty of carbon for industrial biological reaction systems comes from them too.
In wastewater treatment, acetate ions act as an easy electron source for microbes. Denitrification and dephosphorization run faster because of it, so the plant cleans the water in less time. Electroplating plants get the same benefit. So do textile mills and chemical synthesis sites. Leftover acid in the system gets neutralized by the mild weak alkalinity. Through the whole production run, buffer capacity holds the pH steady. Product quality no longer swings from an acid-base imbalance.
Applications
Wastewater Treatment: Here you get a carbon source you can count on. It breaks down on its own inside biological systems that remove nitrogen and phosphorus. Denitrification performs well with it. Treatment results climb high enough to meet discharge limits.
Textile Industry: Precision dyeing work suits it well. Impurity levels stay very low, so fabrics come out without staining defects. Color builds up evenly. The finished dye lot ends up with better quality.
Electroplating: For plating baths, this is a professional pH buffering agent. The pH range the plating reaction needs gets held steady over time. Metal layers come out more even, and they stick better too.
Chemical Synthesis: In this setting it serves as a pH regulator and a reagent of high purity. Fine chemicals get built with it. So do intermediates. Impurity limits in precision chemical work are tight, and it clears them.
Heat Storage Systems: The way it shifts phase in crystalline form does not drift. So it turns up in phase change materials. Thermal storage units used by industry rely on it too. Heat goes in, then comes back out, and very little is lost on the way.
Industrial Buffers: Steady pH buffering protection runs without a break through pharmaceutical intermediate production. Fine chemical processing gets the same cover. Other links in industrial manufacturing do as well.

Certifications & Compliance
All our production procedures strictly comply with the enterprise standard Q/140902ZYH002-2020. Every batch of products will undergo strict laboratory testing on effective content, chloride ions, water-insoluble substances, iron ions and other core indicators to ensure full compliance with standard requirements.
Our production base has passed ISO quality management system certification, realizing standardized and traceable whole-process production control. We support SGS and other authoritative third-party testing services. Meanwhile, we can provide customized KOSHER and HALAL certification documents to meet diverse global market access requirements. We implement strict quality commitment, providing unconditional replacement and return services for non-compliant products.

Packaging Options
Standard Packaging: Moisture-proof bags of 25kg, and every bag carries a food-grade polyethylene inner liner. Moisture stays out. So do pollutants. The product keeps its purity through transport and storage.
Bulk Packaging: Tonnage jumbo bags of 1000kg. These fit large-scale industrial purchasing. Customers feed the line less often, and packaging costs go down.
Moisture barrier performance is strong in both packaging options. Each one keeps the crystal structure intact and holds product quality steady. That guards the goods against contamination and spoilage.

Manufacturing Process
We select national standard high-purity acetic acid and sodium hydroxide as raw materials, and carry out precise neutralization reaction under constant temperature and pressure control to ensure sufficient and stable reaction.
After solution concentration and gradient crystallization treatment, standard trihydrate crystal particles are formed. The optimized centrifugal process precisely controls the moisture content at about 40%, matching the product's core technical indicators.
Through segmented temperature-controlled drying and crystal shaping technology, the product obtains excellent anti-caking performance. Multiple quality inspection nodes are set in the whole production process to strictly abide by Q/140902ZYH002-2020 standards.

FAQ
Q: What is the core advantage of your high-purity industrial grade product?
A: A1: The chloride impurity in our product is kept very low (≤0.03%). Ordinary industrial grades sit at ≤0.2%, so ours is far below that figure. In precision industrial production this keeps impurity interference and quality risks out of the picture.
Q: Can this industrial grade product be used for food processing?
A: A2: This grade is made for industrial use only. Food-grade safety standards are not met by it. Looking for a food-grade version? We supply professional food-grade sodium acetate trihydrate that matches your requirements.
Q: What storage conditions are standard for the long term?
A: A3: Store the product in a clean, dry warehouse with good airflow. Keep the packaging sealed. Moisture makes the product spoil or clump, so keep it away. Acidic substances and strong oxidants should also be kept away from it.
Q: How long is the product valid, and what shelf life does it have?
A: A4: Store it sealed and dry. Its physical and chemical properties stay good that way. Shelf life: 24 months from the production date.
Q: Could you arrange third-party testing and send over the qualification documents?
A: A5: Yes, we can. SGS third-party testing is available. Batch COA reports, enterprise standard documents and other qualification certificates can all be supplied, so customers get what they need for inspection and filing.
