Industrial-grade oxalic acid (also known as ethanedioic acid; molecular formula: H₂C₂O₄·2H₂O) is a widely used organic acid. Thanks to its strong reducing properties and complexing ability, it is frequently used as a metal surface derusting and descaling agent to remove scale and rust from steel and equipment. In the rare earth industry, it serves as a precipitating and separating agent; in textile printing and dyeing, it acts as a bleaching agent and a reducing agent for dyeing (serving as a substitute for acetic acid); in the stone industry, it is used for cleaning, removing yellowing, and polishing marble; and in leather processing, it serves as a tanning auxiliary. It is also extensively used in chemical synthesis, catalyst preparation, and wastewater treatment.
