Overcoming Industrial Acid Challenges with CAS 144-62-7 Oxalic Acid
We’ve witnessed countless production delays caused by inconsistent acid purity—96% vs 99% grades mixing in batches, leading to unpredictable leather polishing results and stone cleaning inefficiencies. Our 12 years in chemical supply have taught us that even 0.5% impurity can disrupt industrial processes, from uneven material etching to increased wastewater treatment costs.
Industrial Grade Oxalic Acid: Your Stable Production Partner
Our Industrial Grade Oxalic Acid 99.6% delivers the consistency modern manufacturing demands. With a monthly production capacity of 5,000 tons and ISO9001-certified facilities in Shandong, we’ve supported leather processing plants across Europe and stone restoration workshops in the Middle East, ensuring steady supply even during peak seasons.
Key Industrial Applications
This versatile dicarboxylic acid excels in leather polishing, where its controlled acidity removes surface impurities without damaging hide fibers. In stone cleaning, it effectively dissolves mineral deposits and rust stains from花岗岩 and marble surfaces. Additional industrial uses include metal surface treatment, textile printing, and as a reducing agent in chemical synthesis processes.
Critical Specifications for Industrial Performance
The 99.6% purity minimizes metallic impurities that cause discoloration in leather finishing, while the medium strong acidity ensures optimal reaction rates without excessive material腐蚀. Its well-defined melting point (101-102ºC) allows precise temperature control in industrial baths, and the 365.10ºC boiling point prevents premature evaporation during high-temperature processes. The white powder form ensures uniform mixing, eliminating the risk of uneven application in stone cleaning formulations.
Reliability That Translates to Cost Savings
Choosing substandard oxalic acid can lead to 15-20% material waste due to inconsistent results and increased rework. Our SGS-tested product reduces these costs by delivering batch-to-batch consistency, supported by full technical documentation. As a direct supplier with hydrolysis production expertise, we eliminate middleman markups while maintaining strict quality control—your assurance of both cost efficiency and performance stability.
Our Quality Commitment
Every production run undergoes HPLC purity analysis, with heavy metal testing conducted by third-party laboratories. Each shipment includes a detailed COA specifying batch-specific parameters, and MSDS documentation tailored to international transport regulations. We maintain a 24-hour technical support line for process optimization advice, and our 30-day quality guarantee ensures replacement of any non-conforming batches—no questions asked.
Certificate of Analysis & Documentation
All orders include a batch-specific Certificate of Analysis with purity test results, solubility data, and impurity profiles. MSDS documents comply with GHS standards, providing comprehensive handling and safety information. For critical applications, we can arrange pre-shipment sample testing through SGS or your preferred laboratory upon request.
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.
Streamlined Order Process
Start by submitting your requirements through our inquiry system, specifying quantity, packaging needs, and target delivery date. We’ll provide a detailed quotation including FOB/CIF pricing options, then arrange sample shipment for your evaluation. Upon approval, production commences with full quality monitoring, and we coordinate logistics through Qingdao, Tianjin, or Shanghai ports for optimal shipping efficiency.
