Oxalic Acid CAS 6153-56-6: Solving Industrial Purity and Supply Challenges
In leather processing and mining operations, inconsistent oxalic acid purity can lead to uneven dye absorption, equipment corrosion from impurities, and production delays due to supply shortages. Having supported industrial clients across 50+ countries for over a decade, we’ve seen how 0.4% purity differences can escalate into 15% higher reject rates in leather tanning or 20% increased acid consumption in mineral processing.
A Stable and Reliable Industrial Grade Oxalic Acid Solution
Our 99.6% Industrial Grade Oxalic Acid addresses these critical pain points through stringent manufacturing control and a scalable supply chain. With a monthly production capacity of 5000 tons and ISO9001-certified processes, we ensure consistent batch quality that meets the demanding standards of leather treatment, mining, and industrial cleaning applications.
Typical Industrial Applications
As a versatile dicarboxylic acid, Oxalic Acid for Mining Applications serves as an effective mineral processing agent, aiding in the extraction of rare earth elements and metal purification through its strong chelating properties. In leather production, it functions as a key deliming and bleaching agent, ensuring uniform fiber structure and consistent color absorption. Its reducing properties also make it valuable for stone cleaning and metal surface treatment in industrial settings.
Why Key Specifications Matter
The 99.6% purity level minimizes heavy metal impurities (below 5ppm) that can compromise leather product quality or contaminate mining output. The fine white powder form ensures rapid dissolution in water, reducing processing time in industrial baths. With a controlled melting point of 101-102ºC, our Oxalic Acid maintains stability during high-temperature reactions, preventing unexpected decomposition that could alter process chemistry. The medium strong acidity (pKa1=1.27) provides optimal pH control without excessive corrosiveness to processing equipment.
What You Gain With Our Industrial Grade Oxalic Acid
Using our 99.6% Oxalic Acid Powder translates to measurable operational benefits: reduced raw material waste by minimizing purification steps, lower equipment maintenance costs from controlled impurity levels, and improved production predictability through consistent batch performance. Compared to lower-grade alternatives, our product reduces leather tanning rework rates by an average of 12% and cuts mining reagent consumption by up to 18%. Backed by SGS certification and full compliance with international chemical transport regulations (UN No. 3261), it ensures smooth customs clearance and regulatory compliance across global markets.
Why You Can Trust Us
Our quality assurance starts with raw material screening and continues through every production stage with real-time HPLC analysis. Each batch undergoes triple testing (initial synthesis, purification, final packaging) and is accompanied by a detailed COA with impurity profiles and performance data. We maintain a 30-day buffer stock to prevent supply disruptions and offer technical support from our team of chemical engineers with 15+ years of industry experience. Our track record includes 98.7% on-time delivery over the past 36 months and a 0.3% product return rate—testaments to our commitment to reliability.
Certificate of Analysis & Documentation
Every shipment includes a batch-specific Certificate of Analysis with purity verification, heavy metal content, and physical property data. MSDS documents compliant with GHS standards are provided in multiple languages, detailing safe handling and emergency procedures. For critical applications, we can arrange third-party testing through SGS or Intertek at the client’s request, with results typically available within 48 hours of sample submission.
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.
How to Place Your Order
