Oxalic Acid 99.6% Industrial Grade (CAS 144-62-7): Addressing Leather Processing and Stone Cleaning Challenges
In leather processing, inconsistent oxalic acid purity often leads to uneven dye absorption and surface defects, while in stone cleaning applications, impurity-laden batches can cause irreversible etching. Over a decade of serving global industrial clients, we’ve witnessed how these issues disrupt production schedules and increase material waste—problems that stem from unreliable sourcing rather than process flaws.
Stabilizing Industrial Processes with High-Purity Oxalic Acid
Our Industrial Oxalic Acid 99.6% delivers the consistency modern manufacturing demands. With a production capacity of 6,000 tons monthly and ISO9001-certified quality control, we ensure each batch meets the same rigorous standards, eliminating the variability that plagues leather tanning and stone restoration workflows. This stability is why over 6,000 industrial customers worldwide trust our supply chain for critical processing materials.
Industrial Applications and Versatility
As a dicarboxylic acid with strong reducing properties, this White Powder Oxalic Acid finds essential use in leather processing for deliming and bleaching, where its controlled acidity ensures proper collagen fiber preparation. In stone cleaning, its ability to dissolve mineral deposits makes it invaluable for restoring marble and granite surfaces. Additional industrial applications include metal surface treatment, mining reagent formulation, and as a reducing agent in chemical synthesis—all strictly for manufacturing and research contexts.
Key Specifications Driving Performance
The 99.6% purity level minimizes metallic impurities that cause discoloration in leather products, while its defined melting point (101-102ºC) ensures predictable dissolution behavior during processing. The medium-strong acidity (pKa1 1.27) provides optimal reactivity without excessive material degradation, a critical factor in stone cleaning where substrate sensitivity varies. Our hydrolysis production method further guarantees low organic residue, preventing unwanted byproducts in downstream reactions.
Risk Mitigation Through Quality Assurance
Choosing substandard oxalic acid risks batch failures, equipment corrosion, and non-compliance with environmental regulations. Our product mitigates these threats through SGS-verified composition, strict heavy metal controls, and batch-specific COA documentation. Unlike suppliers offering ambiguous “industrial grade” products, our 99.6% specification is backed by chromatography testing, ensuring it meets the stringent requirements of automotive leather suppliers and heritage stone conservation projects alike.
Our Commitment to Supply Chain Reliability
Every shipment undergoes triple-stage testing: raw material inspection, in-process monitoring, and final product verification via HPLC. We provide full documentation including MSDS and certificate of analysis with each order, and maintain 30-day buffer stock at major ports (Qingdao, Tianjin, Shanghai) to prevent delivery delays. Our technical team offers pre-purchase application consulting, and we stand behind every batch with a no-questions return policy if specifications are not met—承诺 grounded in a decade of chemical export experience.
Certificate of Analysis & Documentation
Each 25kg bag includes a batch-specific COA detailing purity, moisture content, and impurity levels. MSDS documents are available in multiple languages, covering handling precautions and regulatory compliance. For critical applications, we can arrange third-party testing by SGS or Intertek at the buyer’s request, with results delivered 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.
