The pH of 0.1 mol/L solution is 1.3. Relative density (water=1) 1.653. Melting point 189.5℃.
;Application: Oxalic acid can be used as a reducing agent, bleach, dyeing aid, regulator, additive, etc.
1. Oxalic acid is mainly used in the production of drugs such as antibiotics and ice tablets, as well as solvents, dye reducing agents, tanning agents, etc. for refining rare metals. In addition, oxalic acid can also be used to synthesize various oxalates, oxalates, oxalamide and other products, with the largest production of diethyl oxalate, sodium oxalate and calcium oxalate. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marble, and the bleaching of textiles. Acidity regulator used to synthesize adhesives such as urea-formaldehyde
Resin and
MELAMINE formaldehyde resin. The pharmaceutical industry is used to manufacture oxatetromycin, aureomycin and other drugs.
2. It is mainly used as a reducing agent and bleaching agent, and a mordant in the printing and dyeing industry. It is also used to refine rare metals and synthesize various oxalates, oxalates and oxamide.
3. It is used as an acidity regulator for synthetic adhesives such as urea-formaldehyde resin and melamine formaldehyde resin. Polyvinyl formaldehyde water-soluble adhesive can also be added to improve the drying speed and bonding strength. It is an important organic synthetic raw material and is used to produce various oxalates, oxalates, oxalamides, hydroquinone, quintetrate, mollic acid and other products. The pharmaceutical industry is used to manufacture aureomycin, oxyteramycin, tetracycline, streptomycin, ice tablets, vitamin B12, phenobarbital and other drugs. The printing and dyeing industry is used as a color dye and bleach. The plastics industry is used to produce polyvinyl chloride, amino plastics and urea-formaldehyde plastics. The metallurgical industry is used to produce high-purity nickel, carbon fine rods and precipitate rare earth metals. It is also used as a metal
Detergent, tanning agent, chelating agent, catalyst, anaerobic adhesive and acrylic fast-fixing agent, machined rust remover, electroplating complexing agent, wood bleaching, marble cleaning and oil refining, etc.
4. It can be used as an additive to shampoo in cosmetics, mainly in the manufacture of chemical industry products; in the pharmaceutical industry, it is used in the manufacture of antibiotics and other drugs; it is widely used in the printing and dyeing industry and the leather industry; in oil chemistry, it is used as a refiner for turine alcohol, glycerin and stearate; in addition, it is used in the processing of aluminum products and cemented carbide production.
