Product Description

[basic information]

Sodium metabisulfite is a white or yellow crystalline powder or small crystal with a strong SO2 odor, a specific gravity of 1.4, soluble in water, and the aqueous solution is acidic. When it is in contact with a strong acid, it releases SO2 to form a corresponding salt. When it is left in the air, it oxidizes. It is Na2S2O6, so the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.

[The main purpose]

Chemical industry:

It is used for the production of insurance powder, sulfamethazine, analgin, caprolactam, etc., as well as the purification of chloroform, phenylpropane sulfone and benzaldehyde. The photographic industry is used as a fixative for the fixer. The perfume industry is used to produce vanillin. Used as a preservative for brewing industry, a rubber coagulant and a bleaching agent for cotton bleaching.
