Oxalic Acid Dihydrate 99.6% Purity Rust Remover and Metal Cleaning Agent
Oxalic Acid Dihydrate 99.6% is a premium-grade rust remover and metal cleaning agent with exceptional chelating properties and reducing capabilities. This colorless, crystalline substance is indispensable in metal surface treatment, textile processing, and pharmaceutical synthesis.
Alias: Ethylene Glycolic Acid
English Name: Oxalic acid
Chemical Formula: H₂C₂O₄
Molecular Weight: 90.04
CAS: 144-62-7
Superior Rust Removal Performance
Oxalic acid effectively removes rust through unique chemical interactions with iron oxides, forming water-soluble ferric oxalate complexes that dissolve rust while preserving the underlying base metal. The dihydrate form (C₂H₂O₄·2H₂O) offers optimal stability and solubility for industrial applications.
Industrial Applications
Metal surface treatment and preparation
Aluminum brightening and anodizing
Copper and brass cleaning
Stainless steel passivation
