- Product Description
High-Purity Potassium Ethanoate (Solid) for Industrial Applications – Your Reliable Chemical Solution
SHANXI ZHAOYI CHEMICAL CO., LTD. produces acetate chemicals and ships them abroad. Purity is what the name stands for. Work at the plant began in 1988. That is more than 35 years of hands-on practice. Our base takes up 27,000 ㎡, and both R&D and large-scale output of the acetate series happen there. Every year the plant turns out 150,000 tons. That figure holds steady, and it lets buyers around the world plan their orders. One product we supply is Potassium ethanoate (solid) (CAS NO. 127-08-2). It is a white crystalline organic salt, with a purity of 99% or higher. Water dissolves it quickly. Moisture absorption stays stable. The water solution is mildly alkaline. It buffers well, and it acts as an auxiliary catalyst. Pharmaceutical synthesis is one field that uses it. Farm chemical formulations are another. Industrial pH buffer systems use it too, in markets worldwide.

Key Features & Benefits
This productwas built to handle tough industrial settings and complex production lines. From it, formulators and processors get results they can trust, batch after batch.
Fast Dissolution & Stable Storage Performance: White and uniform, the crystals break apart in water fast and all the way through. Lines that run nonstop, where every minute counts, are a good fit. Moisture pickup stays steady as well. Keep it in a sealed container the standard way, and the product holds its physical state and keeps doing its job.
Mild & Efficient pH Buffering: Add water and the mix turns mildly alkaline. The pH moves in a soft, controlled way. No harsh chemical burn shows up. A steady buffer system forms because of that. It suits pharmaceutical intermediate work, and it suits lab reagents made to an exact spec.
High Purity & Low Contamination Risk: Strict purification steps keep purity very high. Fewer impurities get through. In sensitive industrial work, that counts for a lot. Whether the material goes into industrial catalyst synthesis or into special farm formulas, the quality comes out the same every time. So the production pass rate stays up.

How It Works
Potassium ethanoate (solid) acts quickly through ionic dissociation and chemical reactions. That is the reason so many different jobs open up for it, both in the lab and on the production line.
Stable pH Buffering Mechanism: Drop the product into water and it splits apart, into potassium cations and acetate anions. Those two then build an acid-base buffer that holds steady. Outside pH shifts hardly touch it. Set a level for acidity or alkalinity, and the solution stays there. Experiments and production runs that need tight pH control fit this well.
Efficient Catalytic Acceleration: Inside organic catalytic reactions, acetate ions supply nucleophilic active sites. Reaction kinetics pick up speed fast because of that. Esterification runs quicker. Condensation and other core reactions do too. As a key auxiliary raw material, it carries high-precision pharmaceutical synthesis.
Accurate Ionic Calibration: Potassium ions keep the ionic strength of a solution from drifting. Lab titration analysis and electrochemical testing then work with ionic behaviour that stays stable and is easy to predict. Numbers come out accurate. Run it a second time and you get the same figures.
Applications
Chemical Synthesis: Organic synthesis leans on this inorganic reagent for a key job. Acetate esters get made with it. It also turns up in pharmaceutical intermediates and in raw materials for fine chemicals. Reactions hold a steady, efficient pace once it is in the mix.
Laboratory Analysis: Analytical chemistry puts this material to work as a pH regulator. It also serves as a buffer ingredient. Precision tests call for a pH level that holds still. A steady level makes the test data more accurate.
Pharmaceutical Manufacturing: Drug synthesis and formula development can start with this material, since it counts as high-purity. Plants that turn out pharmaceutical-grade products write strict rules for purity and stability. This material clears those rules.
Industrial Buffer Systems: Textile processing and metal treatment are two of the areas where it gets used, along with other industrial setups. It keeps the pH of a solution steady. That way production quality does not swing around when the acid-base balance goes off.
Agricultural Formulations: These blends show up in slow-release fertilizers built for the job. Potassium gets delivered to the crop, and the supply actually holds up. Nutrients come out at a steady pace. So the plant takes in more of what was spread.
Oilfield Applications: Put it into water-based drilling fluids, and shale stops soaking up water and swelling. The wellbore wall holds its shape. Fewer things go wrong downhole. Work at the site carries on safely, with little wasted effort.

Certifications & Compliance
We implement strict full-process quality control system in all production links. Our factory has passed authoritative ISO quality system certification, and the products hold valid KOSHER and HALAL certificates, fully meeting the access standards of food-grade, pharmaceutical-grade and other high-standard application scenarios.
All production processes strictly comply with international chemical safety and environmental protection regulations, adapting to the market requirements of Europe, America, Asia and other global regions. We can provide complete compliance documents and quality certification materials to support customers' project filing and quality audit work.

Packaging Options
We provide targeted packaging solutions for different procurement volumes and usage scenarios to fully protect product purity and stability during transportation and storage:
Standard Packaging: 25kg paper bags or woven plastic bags with PE inner liners, with excellent moisture-proof and sealing performance, suitable for conventional industrial batch use and laboratory testing.
Bulk & Custom Packaging: We support large-tonnage bulk packaging and personalized customized packaging solutions, which can be matched with customers' automated feeding systems and logistics modes to optimize procurement costs for large-scale production.

Manufacturing Process
Continuous neutralization technology runs our whole line. High-purity acetic acid goes in, together with pharmaceutical-grade potassium hydroxide or potassium carbonate. All through the reaction, temperature stays level. The reaction then goes far enough and stays even. Leftover impurities are lower right from the start.
The crude product then goes through several rounds of recrystallization, filtration and purification. Trace impurities come out completely. Each batch of finished goods also goes to the lab for strict testing. Only when every indicator matches industry standards does it get packed and shipped.
Relying on our 27,000 ㎡ standardized production base and independent quality control laboratory, we realize real-time monitoring of all production links. After decades of process iteration and optimization, our product stability and batch consistency have reached the leading level in the industry.

A: A3: Our pharmaceutical grade matches the standards used in the industry. So does our high-purity grade. Need the paperwork? We can send professional spec documents and certification reports. Then you can see if it works for food-grade use, based on what the customer needs.
Q: For standard delivery, how long does it take?
A: A4: Stock items normally ship in 2-3 weeks. Big custom batches work another way. Production for those gets planned well ahead, and then we confirm the exact delivery time with customers.
Q: Do you hand over full technical documents?
A: A5: Yes. We will provide complete supporting documents such as COA, MSDS and product specification sheets for each shipment to meet your quality inspection and project filing requirements.
