Oxalic acid powder supplier Aojin Chemical offers industrial-grade 99.6% oxalic acid at factory prices. Recently, many customers have asked about the uses of oxalic acid powder. Today, Aojin Chemical, an oxalic acid supplier, will share with you the specific uses of oxalic acid. Oxalic acid, primarily composed of oxalic acid with the chemical formula C₂H₂O₄, is primarily used in industry, daily cleaning, scientific research, and other fields. The details are as follows:
1. Industrial: Core Applications Based on Chemical Properties
Oxalic acid's strong acidity and ability to form soluble complexes or precipitates with metal ions make it highly sought after in industry. Common applications include:
2. Metal Treatment
Rust Removal and Cleaning: Oxalic acid dissolves oxides on metal surfaces (such as iron rust Fe₂O₃ and copper rust CuO), forming soluble oxalates. It is commonly used in the pretreatment of steel and metal parts (such as rust removal before electroplating) and in the refurbishment and cleaning of metalware. 2. Boiler/Pipe Descaling: Oxalic acid reacts with scale components such as calcium carbonate (CaCO₃) and magnesium sulfate (MgSO₄) to form water-soluble calcium oxalate (note: calcium oxalate has low solubility, so the concentration must be controlled to avoid secondary precipitation). It is used for descaling industrial boilers and pipes.
3. Textile and Printing and Dyeing Industry
Bleaching Agent: Oxalic acid has reducing properties, destroying pigments on textiles (such as natural pigments or dye residues in cotton and linen fibers). It is used as an auxiliary bleaching agent (often combined with hydrogen peroxide to enhance bleaching effectiveness).
4. Dyeing Auxiliary: It binds to metal ions (such as iron and copper ions) in fabrics, preventing them from affecting dye color development and improving dyeing uniformity and vividness.
Other Industrial Uses: As a raw material for organic synthesis, it is used in the production of chemical products such as oxalate esters and oxalamides (for example, dimethyl oxalate can be used in the synthesis of pharmaceutical intermediates).
5. In the leather industry, it is used for de-ashing and neutralization during the tanning process, and to adjust the pH value of leather. In summary, oxalic acid powder is a highly functional chemical, with its core applications focused on industrial processing and specific cleaning scenarios.
