Oxalic Acid: Main Applications
Oxalic acid is mainly used in the production of drugs such as antibiotics and menthol, as well as a solvent for refining rare metals, dye reducing agent, and tanning agent. In addition, it can be used to synthesize various oxalates, oxalic acid esters, and oxamides,...
As a diprotic organic acid, oxalic acid contains two carboxyl groups, giving it two ionizable hydrogen atoms. In aqueous solution, it dissociates into oxalate ions and two hydrogen ions, as shown in the following reactions:
Oxalic acid is chemically reactive and can undergo coordination reaction...
Chemical Name of Oxalic Acid
Oxalic acid, also known as ethanedioic acid, is a colorless crystalline organic compound with the chemical formula H₂C₂O₄ and good solubility in water. As an organic acid, it has a wide range of applications, including electroplating, metal cleaning, and textile dyein...

Standards for Industrial Ethanol
Appearance and Odor
The product should be clear and transparent, free of visible impurities. It should have no abnormal odor, no obvious pungent smell, or other unusual odors.
Physical and Chemical Indicators
Ethanol content (C₂H₅OH, mass fraction): ≥ 95.0% (premi...
Disinfection Products
Alcohol with a volume fraction of over 99.5% is called absolute ethanol. In biology, it is used because pigments in chloroplasts are soluble in organic solvents like absolute ethanol (or acetone), so absolute ethanol can be used to extract these pigments.
95% alcohol is used...
Applications of Ethanol
Industrial Raw Materials
Ethanol has a wide range of industrial uses, including:
As a solvent; in organic synthesis; for crystallization of various compounds; as a cleaning agent and extractant.
Edible alcohol can be used to blend white spirits, as an adhesive, and as a so...
Ethanol has a wide range of applications. It can be used to produce acetic acid, beverages, flavors, dyes, fuels, and more. In the medical field, ethanol with a volume fraction of 70%–75% is commonly used as a disinfectant. It also has extensive uses in national defense, chemical industry, health...
