Addressing Industrial Challenges with 99.6% Oxalic Acid (CAS 144-62-7)
In leather processing and stone cleaning operations, inconsistent oxalic acid purity often leads to uneven dye absorption and surface etching variations. Our decade of serving industrial clients across 50+ countries has shown that purity fluctuations above 0.5% can increase reject rates by up to 18% in leather tanning processes, while supply disruptions have delayed production timelines by an average of 14 days for stone restoration projects.
A Stable and Reliable Chemical Supply Solution
Our High Purity Oxalic Acid 99.6% eliminates these challenges through stringent manufacturing controls. With a monthly production capacity of 5000 tons and three loading ports (Qingdao, Tianjin, Shanghai), we ensure consistent supply even for large-scale industrial requirements. This reliability has made us the preferred partner for multinational leather manufacturers and heritage stone conservation projects across Europe and Southeast Asia.
Typical Industrial Applications
As a dicarboxylic acid with strong chelating properties, 99.6% Oxalic Acid serves critical roles in multiple industrial processes. In leather manufacturing, it effectively removes lime deposits from hides during beamhouse operations, preparing collagen fibers for uniform tanning. For stone cleaning applications, its controlled acidity safely dissolves mineral deposits and rust stains from granite, marble, and limestone surfaces without damaging the substrate. Additional industrial uses include metal surface treatment, textile bleaching, and as a reducing agent in chemical synthesis.
Why Key Specifications Matter
The 99.6% purity level ensures minimal impurity interference – iron content below 5ppm prevents catalytic side reactions in leather processing, while chloride levels under 10ppm avoid stone pitting during cleaning. The medium strong acidity (pKa1=1.27) provides optimal reactivity without excessive material damage, crucial for both delicate leather and historic stone substrates. Our product’s consistent melting point (101-102ºC) guarantees uniform dissolution behavior, ensuring batch-to-batch process repeatability that is essential for quality control in industrial production lines.
What You Gain With Our Product
Choosing our White Crystal Oxalic Acid delivers measurable operational benefits: reduced material waste through predictable reaction performance, lower rework costs from consistent quality, and minimized production downtime via reliable supply. Unlike low-purity alternatives that may contain heavy metal contaminants, our ISO9001-certified production meets strict EU REACH standards, eliminating customs clearance delays in European markets. The 25kg packaging format optimizes handling efficiency while maintaining product integrity during storage and transportation.
Why You Can Trust Us
Our quality assurance protocol includes triple-stage testing: raw material inspection via HPLC, in-process monitoring using titration analysis, and final product verification through SGS third-party certification. Each batch comes with a detailed Certificate of Analysis documenting key parameters including purity, moisture content, and heavy metal levels. We maintain a 100% replacement guarantee for any non-conforming shipments, supported by our 10+ years of chemical export experience serving over 6,000 industrial customers worldwide. Our technical team provides pre-purchase specification咨询 and post-delivery usage guidance at no additional cost.
Certificate of Analysis & Documentation
Every delivery includes a batch-specific COA with test results for all critical parameters, along with a comprehensive MSDS containing handling precautions, storage requirements, and emergency procedures. For customers requiring additional verification, we can provide full chromatographic analysis reports upon request. All documentation complies with international trade requirements for chemical shipments, including proper UN3261 classification and HS code 29171110 declaration.
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 purchase by submitting an inquiry with your required quantity and delivery timeline. We can provide a sample for qualification testing upon request, with sample lead times typically 3-5 business days. Once specifications are confirmed, we accept letters of credit or T/T payment terms, with production lead times averaging 7-10 days for standard orders. All shipments include full documentation package for customs clearance, with tracking information provided once goods are dispatched from our facility in Shandong Province.
