Addressing Purity Instability in Leather & Mining Operations with Oxalic Acid Anhydrous 99.6% (CAS 144-62-7)
We've witnessed countless production disruptions in leather tanning and mineral processing facilities—batch-to-batch purity variations causing uneven dye absorption, unforeseen metal precipitation reactions, and costly rework. When 96% vs 99.6% Oxalic Acid Anhydrous gets mixed up, the difference in impurity levels directly impacts cleaning efficiency and reagent consumption rates, turning predictable processes into guessing games.
A Stable Supply Chain for Critical Industrial Processes
Our Oxalic Acid Anhydrous 99.6% delivers the consistency your operations demand. With 10+ years serving 50+ countries, we've optimized our hydrolysis production to maintain strict purity control, supported by a monthly capacity of 5000 tons to prevent supply gaps during peak seasons. Whether you're processing hides or extracting minerals, our product ensures reliable performance in leather cleaning and mining applications.
Industrial Applications & Functional Benefits
As a versatile industrial chemical, Oxalic Acid Anhydrous 99.6% serves as an effective cleaning agent in leather processing, removing lime and mineral deposits from hides while preparing surfaces for uniform tanning. In mining operations, its chelating properties aid in mineral extraction by dissolving carbonate gangues and facilitating metal separation. Its role as a reducing agent also makes it valuable in various industrial cleaning processes, where controlled reactivity is essential.
Key Specifications Driving Process Efficiency
The 99.6% purity level minimizes metallic impurities that could interfere with leather dyeing or mineral flotation, reducing the need for additional purification steps. Its defined melting point (101-102ºC) ensures consistent dissolution behavior in process solutions, while the medium strong acidity provides optimal pH control without excessive corrosivity. The white powder form guarantees uniform mixing, preventing concentration gradients that lead to process inconsistencies. These specifications aren't just numbers—they're the foundation of repeatable industrial performance.
Risk Mitigation Through Quality Assurance
Choosing substandard Oxalic Acid risks more than product quality; it threatens production timelines, increases waste, and exposes operations to regulatory non-compliance. Our Industrial Grade product, certified by ISO9001 and SGS, meets strict impurity thresholds, reducing the likelihood of equipment corrosion or product contamination. With consistent supply from our Shandong production base and multiple loading ports (Qingdao, Tianjin, Shanghai), we eliminate the hidden costs of supply chain disruptions.
Our Quality Commitment: Beyond Compliance
Every batch of our Oxalic Acid Anhydrous undergoes rigorous testing, including composition analysis via HPLC and moisture content verification, with results documented in a detailed Certificate of Analysis (COA). We provide full MSDS documentation for safe handling, and maintain traceability from raw materials to finished product. If specifications don't match our承诺, we offer immediate replacement—no questions asked. Our technical support team is available to assist with application-specific questions, ensuring you get the most from your chemical investment.
Certificate of Analysis & Documentation
Each shipment includes a batch-specific COA with exact purity measurements, impurity profiles, and physical property data. MSDS documents outlining safe handling procedures are provided as standard. For critical applications requiring additional verification, we can arrange third-party testing through SGS at request. Detailed test records remain accessible for 5 years post-delivery, supporting your quality control and regulatory compliance efforts.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
Streamlined Ordering for Industrial Buyers
Initiate your purchase by submitting an inquiry with your required quantity and delivery timeline. We'll provide a detailed quotation including FOB/CIF options, then arrange sample shipment for your testing and approval. Once specifications are confirmed, we process your order and coordinate logistics from our Qingdao, Tianjin, or Shanghai ports. Every order includes complete documentation—COA, MSDS, and customs clearance papers—to facilitate smooth receiving and quality verification.
