Molecular Weight: 126.07 g/mol
Appearance: White transparent crystal or powder (industrial products may be slightly yellow due to impurities)
Odor: Tasteless or slightly sour
Density: 1.65 g/cm³ (20°C)
Melting Point: Dihydrate loses crystalline water at 101-102°C, converts to anhydrous oxalic acid (H₂C₂O₄)
Solubility: Water: ~10g/100mL (20°C), higher in hot water. Ethanol: ~5.7g/100mL (20°C)
Acidity: Binary acid (pKa₁=1.25, pKa₂=4.14), stronger than acetic acid
Reducibility: Oxidized by strong oxidants (e.g., potassium permanganate) under acidic conditions

Oxalic acid is primarily produced by oxidizing carbohydrates or glucose with nitric acid or air in the presence of vanadium pentoxide. Alternative methods include oxidative carbonylation of alcohols to obtain dioxalate esters, which are then hydrolyzed to oxalic acid. Riel Chemical utilizes advanced production techniques to ensure high purity and consistent quality.
