Oxalic Acid 99.6% CAS 144-62-7: Overcoming Industrial Production Challenges
We've witnessed how inconsistent oxalic acid quality disrupts leather tanning processes—impurities causing uneven dye absorption, purity fluctuations leading to batch rejections, and delayed shipments halting production lines. In 10+ years serving leather manufacturers across 50+ countries, these are the recurring pain points that erode profit margins and operational efficiency.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid addresses these challenges through stringent quality control and规模化 production. With a monthly capacity of 6000 tons and ISO9001 certification, we ensure consistent 99.6% purity that meets the rigorous standards of leather tanning, mining, and industrial cleaning applications. This stability translates to predictable production outcomes and reduced waste for your operations.
Typical Industrial Applications
As a dicarboxylic acid, oxalic acid plays a critical role in various industrial processes. In leather tanning, it acts as a deliming agent, effectively removing lime from hides to prepare them for tanning. Its reducing properties make it ideal for metal cleaning and rust removal in mining operations, while its chelating ability aids in stone cleaning and restoration. All applications are strictly limited to industrial manufacturing processes.
Why Key Specifications Matter
The 99.6% purity level is not arbitrary—it minimizes副反应 in leather processing by reducing impurities that would otherwise compromise hide quality. The controlled melting point (101-102ºC) ensures consistent performance in temperature-sensitive reactions, while the medium strong acidity provides optimal deliming efficiency without damaging collagen fibers. Our product's low heavy metal content, verified through SGS testing, meets international export standards, eliminating customs clearance delays for global shipments.
What You Gain With Our Product
Choosing our Ethanedioic Acid means investing in production reliability. Unlike lower-grade alternatives that risk batch failures and increased waste, our consistent purity reduces rework rates by up to 30% in leather tanning operations. With REACH compliance and MSDS documentation, you avoid regulatory penalties and ensure workplace safety. Our stable supply chain, backed by multiple loading ports (Qingdao, Tianjin, Shanghai), eliminates production downtime due to material shortages.
Why You Can Trust Us
Every batch of our oxalic acid undergoes comprehensive testing using HPLC and titration methods to verify purity and composition. We provide a detailed COA with each shipment, including specific gravity, moisture content, and impurity levels. Our production facility in Shandong adheres to GMP-like standards, with full traceability from raw material sourcing to final packaging. If a batch fails to meet your specified requirements, we offer a no-questions-asked replacement policy. Our technical support team, with average 8+ years of industry experience, is available to address application-specific queries.
Certificate of Analysis & Documentation
Each shipment includes a batch-specific Certificate of Analysis detailing test results for purity, moisture, and key impurities. MSDS documents are provided in multiple languages, including English, Spanish, and German, to support global regulatory compliance. For critical applications, we can arrange third-party testing by SGS or Intertek at an additional cost, with results typically available within 5 working days.
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
Initiate your order by submitting an inquiry with your required quantity and delivery location. We'll provide a detailed quotation including FOB/CIF pricing options within 24 hours. For first-time customers, we recommend requesting a 1kg sample for qualification testing before placing bulk orders. Once specifications are confirmed, production typically takes 5-7 days, with shipping times varying by destination port.
