Addressing Critical Challenges in Leather and Mining Operations with 99.6% Oxalic Acid Dihydrate (CAS 144-62-7)
In leather processing, inconsistent acid purity often leads to uneven deliming and collagen damage, while mining operations face productivity losses from low-grade reagents failing to dissolve mineral deposits effectively. We’ve witnessed countless production delays over 10+ years in the industry—batch-to-batch variations in oxalic acid concentration forcing rework, and supply interruptions halting entire production lines.
A Stable and Reliable Chemical Supply Solution
Our 99.6% Oxalic Acid Dihydrate delivers the consistency industrial processes demand. With a production capacity of 5,000 tons/month and ISO9001-certified manufacturing, we ensure uninterrupted supply for leather cleaning and mining operations across 50+ countries. This dihydrate oxalic acid maintains strict quality control from hydrolysis to final packaging, eliminating the variability that disrupts your workflow.
Typical Industrial Applications
As a critical Leather Cleaning Acid, this chemical effectively removes lime deposits and stains from hides without damaging fibrous structures, ensuring uniform tanning results. In the mining industry, it serves as an efficient chelating agent for mineral processing, particularly in separating rare earth elements and dissolving calcium carbonate deposits. Its reducing properties also make it valuable in metal surface treatment and stone cleaning applications.
Why Key Specifications Matter
The 99.6% minimum purity minimizes impurities that cause side reactions in leather processing, such as iron contaminants that discolor hides. Its defined melting point (101-102ºC) ensures predictable dissolution behavior in mining solutions, while the medium strong acidity balance prevents over-etching of leather collagen. The white powder form guarantees easy handling and precise dosing, critical for maintaining process consistency. Our strict solubility control—high in water and ethanol, insoluble in benzene—ensures compatibility with various industrial solvent systems.
What You Gain With Our Product
Choosing our Industrial Grade Oxalic Acid Dihydrate reduces production costs by minimizing rework caused by substandard materials. Unlike lower purity alternatives that introduce process variability, our consistent quality reduces batch failures by up to 30% in leather manufacturing. The SGS-certified composition ensures compliance with international export standards, eliminating customs clearance delays. With stable pricing and reliable supply, you avoid the hidden costs of production downtime and material waste.
Why You Can Trust Us
Every batch undergoes rigorous HPLC testing to verify purity, with full traceability from raw material to final product. We provide a comprehensive COA with each shipment, detailing key parameters like assay value,重金属含量, and moisture levels. Our manufacturing facility operates under strict ISO9001 protocols, with monthly third-party audits by SGS. If any parameter fails to meet specifications, we offer immediate replacement at no cost. Our dedicated technical support team provides guidance on optimal usage concentrations and safety protocols, backed by a decade of industry expertise.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific Certificate of Analysis and MSDS, providing detailed safety and handling information. For critical applications, we can arrange additional testing by independent laboratories at your request. Historical batch data is retained for 5 years, allowing traceability and process optimization over time.
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.
