Addressing Leather Dyeing and Stone Polishing Challenges with 99.6% Oxalic Acid (CAS 144-62-7)
In leather processing, inconsistent acid purity often leads to uneven dye absorption and batch-to-batch color variations, while in stone polishing, impurities in oxalic acid can cause surface etching or discoloration. Over a decade of serving global industrial clients, we’ve witnessed how substandard Ethanedioic Acid disrupts production schedules and increases rework costs—especially when overseas suppliers fail to maintain strict quality control.
A Stable and Reliable Chemical Supply Solution
Our 99.6% Oxalic Acid addresses these critical pain points through rigorous manufacturing standards and consistent batch quality. As a leading chemical export platform with self-operated import-export rights and 10+ years of experience, we ensure stable supply even for large-scale industrial needs, supporting customers across leather manufacturing, stone processing, and mining sectors worldwide.
Typical Industrial Applications
This High Purity Oxalic Acid finds primary use as a Leather Dyeing Acid, facilitating uniform color penetration and fixation in tanning processes. Its chelating properties also make it an effective Marble Polishing Agent, removing mineral deposits and enhancing surface luster without damaging stone integrity. Additional industrial applications include metal cleaning, ore processing, and as a reducing agent in chemical synthesis—all strictly for manufacturing and research purposes.
Why Key Specifications Matter
The 99.6% purity level minimizes副反应 by reducing trace metal impurities that could interfere with dyeing chemistry, while the medium strong acidity ensures controlled reaction rates critical for consistent leather quality. The precise melting point (101-102ºC) guarantees reliable performance in thermal processing steps, and the low moisture content (inherent in our hydrolysis production method) prevents caking during storage—essential for maintaining product flow in automated production lines. These specifications directly translate to reduced material waste and higher process efficiency.
What You Gain With Our Product
Choosing our White Powder Oxalic Acid means avoiding the hidden costs of inferior raw materials: rejected leather batches due to uneven dyeing, stone polishing defects from impurity-induced etching, and production delays from supply interruptions. Our ISO9001-certified manufacturing process ensures compliance with international industrial standards, while our 6000 Tons/Month production capacity guarantees year-round availability—even during peak demand periods. This reliability translates to predictable production scheduling and long-term cost optimization for your operations.
