Production Process

Product application

Oxalic acid can be used as a reducing agent, bleach, dye aid, regulator, additive, etc.

1. Oxalic acid is mainly used in the production of antibiotics and borneol and other drugs, as well as the extraction of rare metal solvents, dye reducing agents, tanning agents, etc. In addition, oxalic acid can also be used to synthesize various oxalate, oxalate and oxamide products, and diethyl oxalate, sodium oxalate, calcium oxalate and other products are the largest. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, cleaning of metals and marbles, and bleaching of textiles. Used in the synthesis of urea formaldehyde resin, melamine formaldehyde resin and other adhesive acidity regulator. The pharmaceutical industry is used to manufacture oxytetracycline, aureomycin and other drugs.

2. It is mainly used as reducing agent and bleach, mordant in printing and dyeing industry, and is also used to extract rare metals and synthesize various oxalates, oxalates and oxalamide.

3.Used as acidity regulator for synthesis of urea-formaldehyde resin, melamine formaldehyde resin and other adhesives. It can also be added to the water-soluble polyvinyl formaldehyde adhesive to improve the drying speed and bonding strength. As an important raw material for organic synthesis, it is used to produce various oxalates, oxalates, oxalides, hydroquinone, pentaerythritone, gallic acid and other products. Pharmaceutical industry for the manufacture of chloromycin, oxytetracycline, streptomycin, borneol, vitamin B12, phenobarbital and other drugs. Printing and dyeing industry used as color aid, bleaching agent. Plastics industry for the production of polyvinyl chloride, amino plastics, urea formaldehyde plastics.
