Product Use Description
Oxalic acid uses
1.as a bleaching agent
Oxalic acid is mainly used as reducing agent and bleaching agent, used in the production of drugs such as antibiotics and borneol, as a solvent for the extraction of rare metals, as a dye reducing agent, and as a tanning agent.
Oxalic acid is also used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marble, and the bleaching of textiles.
It is used for metal surface cleaning and treatment, rare earth element extraction, textile printing and dyeing, leather processing, catalyst preparation, etc.
2. As a reducing agent
In the organic synthesis industry, it is mainly used to produce chemical products such as hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, and gallic acid.
The plastics industry is used in the production of polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer sheets, etc.
The dye industry is used in the manufacture of salt-based magenta green, etc.
In the printing and dyeing industry, it can replace acetic acid and be used as a color developing aid and bleaching agent for pigment dyes.
The pharmaceutical industry is used in the manufacture of chlortetracycline, oxytetracycline, tetracycline, streptomycin, and ephedrine.
In addition, oxalic acid can also be used to synthesize various products such as oxalate, oxalate and oxalamide, among which diethyl oxalate, sodium oxalate and calcium oxalate are the most productive.
3. As a mordant
Antimony oxalate can be used as a mordant, and ferric ammonium oxalate is an agent for printing blueprints.
4. Rust removal function
Oxalic acid can be used to remove rust: take some oxalic acid, make a solution with warm water, apply it on the rust stain and wipe it. Then rub with metallographic sandpaper and finally spray paint.
(Note: Be careful when using, oxalic acid is highly corrosive to stainless steel. Oxalic acid with high concentration is also easy to corrode hands. And the acid oxalate generated is very soluble, but has a certain degree of toxicity. Do not eat it when using 。 After the skin comes into contact with oxalic acid, it should be washed with water in time.)
