What is Xishui used for? What can Xishui be used for?

Sodium sulphite; sodium sulfite

Synonyms: Sulfur Oxygen.

Molecular Formula: Molecular Weight:

CAS Number: 7757-83-7

Properties: Colorless monoclinic crystal. Density.

Soluble in water, its aqueous solution is alkaline; Insoluble in ethanol. Weathered in air and oxidized to sodium sulfate. Loses crystal water at 150.

Reheat to melt into a mixture of sodium sulfide and sodium sulfate. The density of anhydrous. Oxidation is much slower than hydrate, with no change in dry air.

It is prepared by heating the sodium carbonate solution to 40 and saturating it with sulfur dioxide, and then adding the same amount of sodium carbonate solution to crystallize without contact with air. It is used as a reducing agent, preservative, and contrast agent, and is used to make sodium thiosulfate. **Low concentration sulfur dioxide obtained, currently widely used at home and abroad.

Although there are many kinds of technological processes, their basic processes are similar, including sulfur dioxide absorption, sodium bisulfite neutralization and preparation of anhydrous sodium sulfite crystallization. This method is characterized by stable operation and high desulfurization efficiency. The general efficiency can reach 97 98, and the efficiency will not be reduced even when the exhaust gas load changes greatly.

Product use: As a deoxidizer and bleaching agent in the printing and dyeing industry, it is used in the boiling of various cotton fabrics, which can prevent the localization of cotton fiber and affect the fiber strength, and improve the whiteness of the boiled material. It is used as a contrast agent in the photosensitive industry.

It is used in the organic industry as a reducing agent for the production of m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone-1-sulfonic acid, 1-aminoanthraquinone, sodium aminosalicylate, etc., which can prevent the oxidation of semi-finished products during the reaction process. It is used as a lignin remover in the paper industry. It is used as a stabilizer for man-made fibers in the textile industry.

It is used in the electronics industry to manufacture photoresistors. The water treatment industry is used for the treatment of electroplating wastewater and drinking water.

Packaging, storage and transportation: Packed in plastic woven bags or plastic bags lined with polyethylene plastic bags and double-layer kraft paper in the middle. The inner bag is tied or heat-sealed, and the outer bag is firmly seamed.

The net weight of each bag is 50kg. It should be stored in a cool, dry warehouse. The packaging must be sealed and kept out of contact with air to prevent moisture deterioration.

It cannot be stored and mixed with oxidants, strong acids and harmful and toxic substances. This product is deliquescent and should not be stored for a long time. When transporting, it should be protected from rain and sun exposure.

In the event of a fire, water and various fire extinguishers can be used to extinguish the fire.

Physicochemical properties: white powder or hexagonal prismatic crystal. Relative density.

Soluble in water, the aqueous solution is alkaline. Slightly soluble in alcohol. Insoluble in liquid chlorine, ammonia.

It is a strong reducing agent, which reacts with sulfur dioxide to form sodium bisulfite, reacts with strong acid to form corresponding salts and releases sulfur dioxide.

Quality Standard: Industrial Grade: National Standard GB T 9005-88;Photographic grade: GB T 10550-89

Molecular weight: structural formula: consumption quota: soda ash solution absorption method.

Soda ash (Na2CO3 100% count).

Sulfur (98% meter).

Caustic soda (NaOH 100% count).
