Oxalic Acid: Main Applications
Oxalic acid is mainly used in the production of drugs such as antibiotics and menthol, as well as a solvent for refining rare metals, dye reducing agent, and tanning agent. In addition, it can be used to synthesize various oxalates, oxalic acid esters, and oxamides, among which diethyl oxalate, sodium oxalate, and calcium oxalate have the largest output. It is also applied in the production of cobalt-molybdenum-aluminum catalysts, cleaning of metals and marble, and bleaching of textiles. It serves as an acidity regulator for adhesives like urea-formaldehyde resin and melamine-formaldehyde resin. In the pharmaceutical industry, it is used to manufacture drugs such as terramycin and aureomycin.
