Oxalic Acid

Oxalic acid is an organic substance and a metabolite of organisms. It is a medium-strong acid that is widely distributed in plants, animals and fungi and plays different functions in different organisms. Studies have found that more than 100 plants are rich in oxalic acid, especially spinach 、 Amaranth 、 beet 、 purslane 、The highest content is found in plants such as taro, sweet potato and rhubarb. Since oxalic acid can reduce the bioavailability of mineral elements and easily forms calcium oxalate with calcium ions in the human body, leading to kidney stones, oxalic acid is often considered to be a mineral element absorption and utilization.

Specific uses:

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 drugs such as antibiotics and borneol, as well as solvents for refining rare metals, dye reducing agents, tanning agents, etc. In addition, oxalic acid can also be used to synthesize various oxalic acid esters, oxalates and oxalamides, with diethyl oxalate, sodium oxalate, calcium oxalate, etc. having the largest output. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, cleaning of metals and marble, and bleaching of textiles. It is used as an acidity regulator for synthesizing adhesives such as urea-formaldehyde resins and melamine formaldehyde resins. It is used in the pharmaceutical industry to manufacture drugs such as oxytetracycline and chlortetracycline.

2. It is mainly used as a reducing agent and bleaching agent, a mordant in the printing and dyeing industry, and is also used to refine rare metals and synthesize various oxalates, oxalates and oxalamides.

3. It is used as an acidity regulator for synthetic urea-formaldehyde resins, melamine formaldehyde resins and other adhesives. It can also be added to polyvinyl formal water-soluble adhesives to increase drying speed and bonding strength. It is an important organic synthetic raw material used in the production of various oxalates, oxalates, oxalamides, hydroquinone, pentaerythritol, gallic acid and other products. The pharmaceutical industry is used to manufacture chlortetracycline, oxytetracycline, tetracycline, streptomycin, borneol, vitaminsB12、Phenobarbital and other drugs. In the printing and dyeing industry, it is used as a coloring agent and bleaching agent. In the plastics industry, it is used to produce polyvinyl chloride, amino plastics, and urea-formaldehyde plastics. In the metallurgical industry, it is used to produce high-purity nickel, carbon rods, and precipitated rare earth metals. It is also used as a metal washing agent, tanning agent, chelating agent, catalyst, inhibitor of anaerobic adhesives and acrylic fast-setting adhesives, machining rust remover, electroplating complexing agent, wood bleaching, marble cleaning, and oil refining.

4. In cosmetics, it can be used as an additive for shampoo and is mainly used in the manufacture of chemical industry products. In the pharmaceutical industry, it is used to manufacture antibiotics and other medicines. It is widely used in the printing and dyeing industry and the leather industry. In oil and fat chemistry, it is used as a refining agent for pine oil, glycerin and stearate. In addition, it is used in aluminum product processing and cemented carbide production.
