Industrial Grade Oxalic Acid 99.6% (CAS 144-62-7): Solving Purity and Supply Challenges in Manufacturing
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity—fluctuations as small as 0.3% can trigger unexpected副反应 in leather dyeing baths or leave residues on stone surfaces during cleaning processes. Overseas buyers often struggle with batch-to-batch variations that make quality control a nightmare, not to mention the logistical headaches of securing reliable shipments from China.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid 99.6% addresses these critical pain points with a production process refined over 10 years of serving 50+ countries. With a monthly capacity of 6000 tons and strategic loading ports in Qingdao, Tianjin, and Shanghai, we ensure consistent supply even for large-scale industrial orders. The white powder form guarantees easy handling and precise dosing, whether for leather processing lines or stone restoration projects.
Typical Industrial Applications
As a dicarboxylic acid with medium strong acidity, this oxalic acid finds essential use in leather dyeing for pH adjustment and stain removal, ensuring uniform color absorption across hides. In stone cleaning, its chelating properties effectively dissolve mineral deposits without damaging delicate surfaces. Additional industrial applications include metal surface treatment, mining operations, and as a reducing agent in chemical synthesis processes—all strictly for industrial manufacturing purposes.
Why Key Specifications Matter
The 99.6% purity level is critical for minimizing副反应: lower grades often contain chloride impurities that can corrode equipment or alter reaction kinetics. Our precise melting point range (101-102ºC) indicates minimal water content, ensuring stability in storage and predictable dissolution rates in aqueous solutions. The verified solubility profile—readily dissolving in water and ethanol while remaining insoluble in benzene—allows for flexible formulation across different industrial processes. Each batch maintains consistent density (1.772 g/cm³), a key factor in volumetric dosing accuracy for automated production lines.
What You Gain With Our Product
Choosing our Ethanedioic Acid for Industrial Use means eliminating the hidden costs of substandard materials: reduced reject rates in leather production, fewer rework cycles in stone cleaning, and minimized equipment maintenance from impurity buildup. Our ISO9001-certified production ensures compliance with international industrial standards, while SGS third-party testing provides objective quality verification. Unlike unreliable suppliers, our stable monthly capacity guarantees your production schedule won’t be disrupted by material shortages.
Why You Can Trust Us
Every batch undergoes rigorous testing including titration for purity, FTIR spectroscopy for structural confirmation, and heavy metal analysis to ensure compliance with export requirements. We provide a complete Certificate of Analysis (COA) with each shipment, detailing test results for key parameters like assay value, moisture content, and insoluble matter. Our production facility maintains full traceability from raw material intake to final packaging, and we offer technical support to help optimize your application processes. If any batch fails to meet specifications, we guarantee replacement or full refund—no questions asked.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with detailed test results and compliance statements. MSDS documents are provided in multiple languages, containing comprehensive safety handling instructions and regulatory information. For critical applications, we can arrange for independent third-party testing at an accredited laboratory, with results delivered prior to shipment.
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
Start by submitting an inquiry with your required quantity and delivery terms (FOB/CIF available). We can arrange for sample delivery for qualification testing, typically within 3-5 business days. Once specifications are confirmed, standard lead time for production is 7-10 days, with flexible shipping options from our Qingdao, Tianjin, or Shanghai ports. All orders include full customs documentation and our quality guarantee.
