Oxalic Acid 99.6% (CAS 144-62-7): Eliminating Industrial Process Disruptions
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity—1% fluctuations leading to leather tanning defects, 0.5% impurity spikes ruining stone cleaning solutions, and supply chain gaps halting manufacturing lines. For 10+ years, our technical team has collaborated with leather processors across Turkey and stone fabricators in Italy to resolve these exact challenges through precision manufacturing.
A Stable Supply Chain for Critical Industrial Processes
Our Industrial Oxalic Acid delivers the consistent 99.6% purity your operations demand, backed by a 6,000 tons/month production capacity that ensures year-round availability. As a leading chemical export platform with 10+ years of experience serving 6,000+ global industrial customers, we’ve optimized our hydrolysis process to eliminate batch-to-batch variations, directly addressing the reliability issues plaguing chemical imports.
Core Industrial Applications
This High Purity Oxalic Acid finds essential use in leather processing for deliming and bleaching, where its controlled acidity ensures uniform hide treatment without over-etching. In stone cleaning, its strong chelating properties effectively remove mineral deposits and rust stains from granite and marble surfaces. Additional industrial applications include metal cleaning, textile dyeing, and as a reducing agent in chemical synthesis processes—all strictly for manufacturing purposes.
Why Technical Specifications Drive Performance
The 99.6% purity threshold is critical for minimizing副反应 in leather processing; lower grades introduce sulfur compounds that discolor finished products. Our product’s defined melting point (101-102ºC) ensures consistent dissolution behavior in industrial baths, while its solubility profile (readily soluble in water, insoluble in benzene) prevents solvent contamination in multi-step processes. The medium strong acidity balances reactivity and safety, reducing equipment corrosion compared to stronger mineral acids while maintaining cleaning efficacy.
Risk Mitigation Through Quality Assurance
Choosing substandard oxalic acid risks production rejects, equipment damage, and compliance violations. Our ISO9001-certified manufacturing ensures heavy metal levels below 5ppm, meeting EU REACH standards for export markets. Each batch undergoes SGS third-party testing, guaranteeing that Cleaning Stones Oxalic Acid from our facility performs identically—batch after batch—eliminating the hidden costs of rework and material waste.
Our Quality Commitment
We implement a triple-inspection protocol: raw material testing upon arrival, in-process sampling during hydrolysis, and final analysis before packaging. Every shipment includes a batch-specific COA with purity chromatograms and impurity profiles. Our lab maintains HPLC and FTIR instruments calibrated to USP standards, allowing us to provide detailed spectral data for your quality control verification. If any parameter fails to meet specifications, we arrange immediate replacement at no cost—no questions asked.
Certificate of Analysis & Documentation
Each delivery includes a comprehensive COA with actual test results for purity, moisture, iron, and chloride content. MSDS documents are provided in English, German, and Spanish, detailing safe handling procedures and regulatory compliance. For critical projects, we can arrange pre-shipment sample testing at an independent laboratory of your choice, with test costs refunded upon order confirmation.
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 an inquiry with your required quantity and delivery port (Qingdao, Tianjin, or Shanghai). We’ll provide a detailed quotation including FOB/CIF pricing and lead times within 24 hours. Request a 500g sample for qualification testing—we cover shipping costs for orders exceeding 10 tons. Once specifications are confirmed, production begins immediately, with full documentation package issued upon shipment.
