Product Description

Product Description

 

Chemical formula: NA2S2O5
English name: Sodium metabisulfite
Molecular weight: 190.10

Physical and chemical properties
1.Appearance: White or slightly yellow crystalline powder.
2.Odor: There is a strong irritant odor
3.Solubility: Easily soluble in water, its aqueous solution is acidic. The solubility in water increases with temperature, and at 20 ºC, the solubility is about 64g/100mL of water. It is also soluble in glycerol and slightly soluble in ethanol.
4.Density: Approximately 1.48g/cm ³
5.Stability: It is easily oxidized in air, and when exposed to moisture or humid air, it will slowly oxidize and decompose, and generating sodium sulfate. When heated to around 150 ºC, it will decompose and produce products such as sodium sulfate.

Application

 

1. Food processing industry: As a food additive, it is mainly used for bleaching, preservation, antioxidation, and freshness preservation of food. For example, in the preservation and processing of fruits and vegetables, it can inhibit microbial growth and enzymatic browning reactions; In the process of wine making, it is used for sterilization and antioxidation, to prevent wine from spoiling and oxidation discoloration; In the processing of candied fruits, dried fruits and other foods, it plays a role in bleaching and preservation. But when using, it is necessary to strictly follow the standards for the use of food additives to ensure food safety.

2. Chemical industry: It is an important reducing agent and sulfonating agent. In the printing and dyeing industry, it is used in the dyeing process of reducing dyes to soluble chromophores, which can better penetrate into the interior of fibers for dyeing; In organic synthesis, as a sulfonating agent, it participates in the sulfonation reaction of certain compounds to prepare organic compounds containing sulfonic acid groups; It can also be used to treat chromium containing wastewater, reducing hexavalent chromium to trivalent chromium for subsequent precipitation removal.

3. Pharmaceutical industry: used in the synthesis and refining process of drugs. For example, in the production of certain antibiotics, vitamins, and other drugs, they are used as reducing agents or antioxidants to prevent the drugs from being oxidized and deteriorated during synthesis or storage, ensuring the quality and stability of the drugs.

4. Paper industry: used for bleaching and steaming processes of pulp. In the bleaching process, it can be used as a reducing agent to remove residual lignin from pulp and improve the whiteness of paper; During the steaming process, it can inhibit the growth of microorganisms, reduce pulp spoilage and deterioration, and help improve the strength and quality of paper.

5. Leather industry: used for processes such as depilation, tanning, and bleaching of leather. During the hair removal process, it can make it easier for hair to fall off from the leather; During the tanning and bleaching process, it plays a reducing and antioxidant role, improving the quality and appearance of leather.
