Oxalic Acid 99.6% CAS 144-62-7: Solving Industrial Purity and Supply Challenges
In over a decade of serving chemical processors across 50+ countries, we’ve witnessed how inconsistent oxalic acid purity disrupts leather tanning cycles—causing uneven dye absorption and expensive rework. Researchers repeatedly report batch-to-batch variations derailing their stone cleaning formulations, while manufacturers struggle with unreliable suppliers missing production deadlines during peak seasons.
Stabilized Supply for Critical Industrial Processes
Our Oxalic Acid 99.6% addresses these pain points through consistent high purity and a 5000 Tons/Month production capacity, ensuring uninterrupted supply even for large-scale leather processing lines and mining operations. As a leading chemical export platform with self-operated import-export rights, we’ve established robust logistics channels through Qingdao, Tianjin, and Shanghai ports to minimize delivery delays.
Industrial Applications and Functional Benefits
As a dicarboxylic acid with medium-strong acidity, this industrial-grade oxalic acid serves three primary functions: leather processing (deliming and bleaching), stone cleaning (removing mineral deposits and rust stains), and as a reducing agent in mining operations. Its solubility in water and ethanol allows easy integration into aqueous processing solutions, while insolubility in benzene ensures stability in specific industrial formulations.
Key Specifications Impacting Process Reliability
The 99.6% purity level is critical for reducing副反应 in leather tanning, where trace impurities can alter pH levels and affect collagen structure. A precisely controlled melting point (101-102ºC) ensures consistent performance in thermal processing steps, while the 1.772 g/cm³ density guarantees accurate dosing in automated production systems. The medium strong acidity strikes a balance between effective mineral dissolution for cleaning stones and controlled reactivity to prevent substrate damage.
Quality Assurance: From Production to Delivery
Choosing certified Oxalic Acid minimizes risks associated with substandard materials—such as equipment corrosion from excessive chloride content or product discoloration from heavy metal impurities. Our ISO9001-certified production process includes rigorous SGS testing, with each batch accompanied by a Certificate of Analysis (COA) verifying key parameters. This commitment to quality has made us the preferred supplier for multinational industrial enterprises seeking reliable chemical raw materials.
