Oxalic acid, or oxalic acid, is one of the simplest organic dibasic acids. Structure simple HOOCCOOH. It is generally colorless transparent crystal, oxalic acid plays an important role in industry, oxalic acid can remove rust. Oxalates are found throughout nature, often in the form of oxalates in the cell membranes of plants such as corydoras, sheep's shoe, sorrel, and sorrel. Almost all plants contain oxalates, which are metabolites of purines in dihydrogen.
Used as a complexing agent, masking agent, precipitating agent, reducing agent.
Pharmaceutical industry for the manufacture of chloromycin, oxytetracycline, streptomycin, borneol, vitamin B12, phenobarbital and other drugs.
Printing and dyeing industry used as color aid, bleach, pharmaceutical intermediates.
Plastics industry for the production of polyvinyl chloride, amino plastics, urea formaldehyde plastics.
Used as a catalyst for the synthesis of phenolic resin, and also as a pH regulator for the synthesis of urea formaldehyde resin and melamine formaldehyde resin.
It is used in the production of cobalt-molybdenum-aluminum catalysts, cleaning of metals and marbles and bleaching of textiles.
Used for metal surface cleaning and treatment, rare earth element extraction, textile printing and dyeing, leather processing, catalyst preparation, etc.
In the organic synthesis industry, it is mainly used in the production of hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, gallic acid and other chemical products.
Plastics industry for the production of polyvinyl chloride, amino plastics, urea-formaldehyde plastics, paint chips and so on. The dye industry is used to manufacture base green and so on.
It is used to synthesize various oxalates, oxalates and oxalamide products. It can be used to remove rust.
