Overcoming Stone Cleaning Challenges with 99.6% Oxalic Acid CAS 144-62-7
In industrial stone processing, inconsistent cleaning results often stem from low-purity acid solutions that leave residues or cause uneven etching. We’ve witnessed manufacturing delays when suppliers fail to maintain stable oxalic acid concentrations, leading to batch-to-batch variations that disrupt production schedules. For research institutions, trace impurities in lower-grade acids can compromise experimental reproducibility—a critical issue in material science studies.
A Stable and Reliable Chemical Supply Solution
Our 99.6% Oxalic Acid (CAS 144-62-7) addresses these challenges through rigorous purification processes that ensure consistent quality across every batch. With over 10 years of chemical manufacturing experience and partnerships with 6,000+ industrial customers worldwide, we understand the importance of supply chain reliability. Whether for large-scale stone cleaning operations or precision laboratory research, our industrial-grade oxalic acid delivers the stability professionals demand.
Typical Industrial Applications
As a versatile dicarboxylic acid, 99.6% Oxalic Acid finds critical use in multiple industrial sectors. In stone processing, its chelating properties effectively remove mineral deposits and rust stains without damaging substrate integrity. It serves as a reducing agent in metallurgical processes, a cleaning agent in leather production, and a key intermediate in mining operations. This industrial oxalic acid is also utilized in water treatment and chemical synthesis, providing essential support across manufacturing ecosystems.
Why Key Specifications Matter
The 99.6% purity level minimizes副反应 risks in chemical synthesis by reducing contaminant interference. Its medium-strong acidity ensures controlled reactivity—strong enough for effective stone cleaning yet manageable for safe handling when following proper protocols. The precise melting point (101-102ºC) is crucial for temperature-sensitive processes, while the 1.772 g/cm³ density allows accurate volumetric dosing in industrial mixing systems. Each specification is calibrated to meet strict industrial standards, ensuring optimal performance in your specific application.
What You Gain With Our Product
Choosing our Industrial Grade Oxalic Acid means investing in production efficiency. High purity reduces raw material waste by ensuring complete reaction conversion, while strict quality control lowers the risk of defective finished products. Compared to lower-grade alternatives, our ISO9001-certified product minimizes equipment corrosion and maintenance costs. With a monthly production capacity of 6,000 tons, we guarantee consistent supply even for large-scale operations, eliminating the production delays caused by material shortages.
Why You Can Trust Us
Our quality assurance process includes comprehensive testing via HPLC and titration methods for each production batch. Every order includes a detailed Certificate of Analysis (COA) with actual test results, not generic values. We provide full MSDS documentation to ensure compliance with global safety regulations. Our 10+ years in chemical export have earned us SGS certification and long-term partnerships with multinational corporations. Should any product fail to meet specifications, we offer unconditional replacement—no questions asked.
Certificate of Analysis & Documentation
Every shipment includes a batch-specific COA with purity testing, moisture content, and impurity profiles. MSDS documents provide detailed safety handling instructions tailored to industrial environments. For critical applications, we can arrange third-party testing by SGS upon request. Historical batch data is retained for 5 years, allowing traceability for quality control audits.
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.
