Oxalic acid can be used as a reducing agent, bleaching agent, dyeing aid, regulator, additive, etc.
1. Oxalic acid is mainly used in the production of antibiotics and borneol and other drugs, as well as solvents, dyes, reducing agents, tanning agents, etc. for refining rare metals. In addition, oxalic acid can also be used to synthesize various oxalates, oxalate and oxalamide products, with diethyl oxalate, sodium oxalate, calcium oxalate and other products being the largest. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marbles, and the bleaching of textiles. It is used as an acidity regulator for the synthesis of urea-formaldehyde resin, melamine formaldehyde resin and other adhesives. It is used in the pharmaceutical industry to manufacture drugs such as oxytetracycline and chlortetracycline.
2. Mainly used as reducing agent and bleaching agent, mordant in printing and dyeing industry, also used in refining rare metals, synthesizing various oxalates, oxalate and oxalamide, etc.
3. Used as an acidity regulator for synthetic urea-formaldehyde resin, melamine formaldehyde resin and other adhesives. It can also be added to polyvinyl formaldehyde water-soluble adhesive to improve drying speed and bonding strength. It is an important raw material for organic synthesis, which is used in the production of various oxalate, oxalate, oxalamide, hydroquinone, pentatetrastery, gallic acid and other products. It is used in the pharmaceutical industry to manufacture drugs such as chlortetracycline, oxytetracycline, tetracycline, streptomycin, borneol, vitamin B12, phenobarbital, etc. In the printing and dyeing industry, it is used as a chromogenic dyeing aid and bleaching agent. The plastics industry is used to produce polyvinyl chloride, amino plastics, urea-formaldehyde plastics. The metallurgical industry is used to produce high-purity nickel, carbon rods and precipitated rare earth metals. It is also used as metal detergent, tanning agent, chelating agent, catalyst, anaerobic adhesive and acrylic fast-setting adhesive polymerization inhibitor, machining rust remover, electroplating complexing agent, wood bleaching, marble cleaning and oil refining.
4. It can be used as an additive in shampoo in cosmetics, mainly used in the manufacture of chemical industry products; used in the pharmaceutical industry to manufacture antibiotics and other medicines; The printing and dyeing industry and leather industry are widely used; used in oleochemistry as terpineol, glycerol and stearate refined preparations; In addition, it is used in aluminum products processing and cemented carbide production.
