Application

Rare earth industry

Oxalic acid is an important precipitation material for the extraction, separation and purification of ion-type rare earth minerals, especially for the purification of high-end rare earth elements such as lanthanum and europium. In the mining and separation of medium and heavy rare earth ore.

Pharmacy industry

Adjust the PH value, and generally fermentation is carried out in an acidified environment. It is used for acidification in the production process of chlortetracycline, oxytetracycline, chunremycin, streptomycin, vitamin B2 and other drugs.

Printing and dyeing industry

printing and dyeing industry as dye auxiliaries; Can be used as bleach to remove the rust on the surface of the fabric;

Rust (Fe2O3) is an alkaline oxide, can react with acid, and rust has oxidation, oxalic acid has reducibility, they can produce chemical reactions

4.Electronic industry

Used for the preparation of chemical raw materials for ceramic capacitors.Purified oxalic acid is a high purity oxalic acid produced by industrial oxalic acid refining, the quality index is higher than the national standard (GB/T1626-88), compared with industrial oxalic acid, metal ion impurity content is low, productivity performance is more superior. Purified oxalic acid is used in the electronics industry to process electronic materials, clean circuit boards, etc.

Oxalic acid

FAQ

Q1: What are the different forms of Oxalic Acid?

A: There are industrial grade and refined grade oxalic acid(H2C2O4·2H2O）, as well as anhydrous Oxalic acid（H2C2O4）

Q2: Is oxalic acid safe to use?

A: Contact with skin and eyes should be avoided when using oxalic acid, and appropriate safety precautions should be taken, including the use of personal protective equipment and adequate ventilation.

Can oxalic acid be used for cleaning?

A: Yes, oxalic acid is a weak acid, which is not easy to harm people and not easy to corrode. It is often used for metal surface treatment and grinding and polishing.
