SODIUM SULFITE ANHYDROUS


Sodium Sulfite Anhydrous / Sodium Sulphite

Sodium sulfite Application:

1. In the field of water treatment

as the deoxidant of boiler water and oilfield flooding;

as antichlor for municipal and industrial water;

as the raw material for the production of sodium thiosulfate;

as the stabilizer of viscose acetal fibre;

as the bactericide of beer bottle.

2. In food industry: as bleaching agent, preservative, bulking agent, antioxidant and for the medicine synthesis

3. As analytical reagent, light dependent resistor materials and base solution of polarographic analysis

4. As antioxygen of cosmetics, mainly for hair dye cosmetics

5. As reducing agent of spice, dye and so on

6. In textile industry: as bleacher and deoxidier for fabric

7. In paper industry: as lignin removal agent.

Physical and chemical properties:
White crystalline or powder form; triangular prism crystal shape; alkaline water solution with pH at 9 – 9.5; The highest water solubility is about 28% with temperature at 33.4°C. When exposed to air, it is oxidized to form sodium sulfate. When heated to high temperature, it decomposes to form sodium sulfide; Density: 2.633(15.4°C), Refractive Index: 1.565; Molecular Weight: 126.04.

3.Molecular formulaNa2SO3
5. CAS No7757-83-7
6. HS CODE28321000
7. EINECS No231-821-4

Application:
It is used in dyeing industry as deoxidizer and bleaching agent for a variety of cotton fabric treating and scouring, which can prevent fabrics from local oxidation and deterioration of fibre strength. In photographic industry it is used as a reagent. In organic industry it is used as reducing agent in production of m-phenylenediamine, 25 - bared oxazolone, amino salicylic acid, etc. Textile industry uses it as a stabilizer for synthetic fibre. Other applications include various uses in paper mills, electronic industry, water treatment, etc.
