Oxalic acid, chemical name oxalic acid, is a naturally occurring organic dicarboxylic acid and an important raw material in chemical production. This product is high-purity crystalline oxalic acid with a purity of more than 99.6%, excellent quality and stable performance. It is widely used in many industrial fields such as metal polishing, rare earth refining, pharmaceuticals, textile printing and dyeing, chemical synthesis, etc. It uses 25 kg standard packaging for easy storage and transportation.

Applications：

Industrial field

Metal polishing: bright treatment of stainless steel and aluminum alloy surface

Rust removal: converting rust into soluble iron oxalate

Rare earth refining: precipitation and separation of rare earth elements such as lanthanide elements

Textile bleaching: decolorization of denim and wool

Wood bleaching: removal of pigments on the surface of wood (such as oak)

Chemical and pharmaceutical

Chemical synthesis: production of oxalates, oxalates and dye intermediates

Pharmaceutical raw materials: antibiotic synthesis intermediates (such as oxytetracycline)

Laboratory reagents: potassium permanganate titration reducing agent

Cleaning and environmental protection

Boiler descaling: dissolving calcium carbonate scale

Stone cleaning: removing rust stains on marble

Wastewater treatment: precipitation of heavy metal ions (such as calcium and magnesium)

Safety Notes:

Sublimation characteristics: Oxalic acid sublimates directly at 280°C (without passing through the liquid state), so high temperature storage should be avoided.

High water solubility: 895 grams of oxalic acid can be dissolved per liter of water at 20°C, suitable for preparing solutions.

Safe storage: Please place in a sealed container at room temperature, away from light and moisture (may agglomerate after moisture absorption).

Corrosive warning: Flash point 249°C, keep away from fire; vapor irritates the respiratory tract.
