    Sodium chlorite Raw Materials

    Sodium chlorite CAS 7758-19-2 has two kinds of anhydrous salt and trihydrate salt. Anhydrous salt. Colorless cubic crystal system flaky crystals. Odorless or slightly odorless. Slightly deliquescent. Relative molecular mass 90.45.

    Applications / Functions of Sodium chlorite powder

    1. Sodium chlorite powder is used in the bleaching of pulp, fiber, flour, starch, oil and grease, drinking water purification and sewage treatment, leather dehairing and making chlorine dioxide solution.
    2. Sodium chlorite Raw Materials is used as bleaching agent, decolorant, poison remover, dye pulling agent, etc.
    3. Sodium chlorite CAS 7758-19-2 is used for drinking water purification, no residual chlorine flavor, sewage treatment with sterilization, phenol removal, deodorization. This product is also a highly effective bleaching agent, used to bleach fabrics, fibers, pulp, with the characteristics of small damage to the fiber.
    4. Sodium chlorite CAS 7758-19-2 is a high efficient bleaching agent and oxidizer. Mainly used as pulp, paper and various fibers, such as cotton, hemp, reed. It can also bleach sugar, flour, starch, grease and wax. Also used for leather dehairing, surface treatment of certain metals, drinking water purification and sewage treatment. It can be used as a pulling agent for cathodendrin dyeing.
    5. Sodium chlorite powder is used as bleaching agent in food industry.
    6. Sodium chlorite Raw Materials is a new type of high efficiency bleaching agent and oxidizing fungicide.
    7. Sodium chlorite Raw Materials is a high efficient bleaching agent and oxidizing agent. It is used for bleaching pulp and various fibers, such as cotton, hemp, mulberry, reed, viscose fiber and so on. It can also be used to bleach sugar, flour, starch, ointment, wax and grease. It is also used for leather dehairing, surface treatment of certain metals, drinking water purification and sewage treatment. It can also be used to purify trace nitric oxide in coke oven gas.

    Physicochemical Property of Sodium chlorite powder

    Sodium chlorite CAS 7758-19-2 White crystal or crystalline powder. Slightly hygroscopic. Soluble in water.

    production methodprocess of Sodium chlorite powder

    Industrial production is hydrogen peroxide method and electrolysis method. Hydrogen peroxide method see Sodium chlorite powder, the difference is to add arsenic remover and heavy metal remover for solution purification, filtration, removal of arsenic and heavy metals and other impurities.

    Sodium chlorite CAS 7758-19-2

    • Hydrogen peroxide method will first dissolve sodium chlorate with water to become a solution containing sodium chlorate 250g / L, add chlorine dioxide generator, and then sulfuric acid into 4 mol / LH2SO4. sulfur dioxide and air mixture and 4 mol / LH2S04 were added to the chlorine dioxide generator for the reaction, the resulting chlorine dioxide gas is passed into the three series-connected bubbling absorber tower, with 27.5% of the Hydrogen peroxide, 18% ~ 20% liquid caustic soda for reaction, the resulting solution contains NaClO2140 ~ 160g / L. After precipitation, the clear liquid is liquid sodium chlorite products. After evaporation and concentration to sodium chlorite solution concentration of 350 ~ 400g / L, after cooling crystallization, filtration, drying, to produce solid Sodium chlorite CAS 7758-19-2.
    • Electrolysis method will dissolve sodium chlorate in water and sulfuric acid to form a mixed acid, which contains sodium chlorate 260g/L, add chlorine dioxide generator, and then sulfur dioxide and air mixture (containing sulfur dioxide 8% to 10%) into the chlorine dioxide generator for reaction, resulting in 15% of the chlorine dioxide gas is passed into the cathode chamber of the electrolysis tank, in the anode chamber continuously add brine and distilled water for electrolysis, to generate chlorite Sodium chlorite solution, the sodium chlorite content of about 20%. After removing trace free chlorine dioxide, it is spray dried at 130℃. Or through evaporation and concentration, cooling and crystallization, filtration and drying, Sodium chlorite Raw Materials is produced.
    • Electrolysis method in the cation exchange membrane separated by the three-chamber electrolyzer, chlorine dioxide gas (content of about 15%, ClO2: Cl2 molar ratio of not less than 15:1) into the cathode chamber, dissolved in the solution at about 30 ℃ from the cathode to obtain chlorite, the anode chamber is constantly passed into the sodium chloride solution, chloride ions release electrons into the chlorine gas escapes. Sodium ions, on the other hand, under the action of DC electric field, pass through the anode membrane into the cathode chamber and combine with chlorite root as sodium chlorite. The solution content of 17% to 23%, after removing trace chlorine dichloride, spray drying that is the finished product. Hydrogen peroxide method with air to dilute the raw material chlorine dioxide to about 10%, into the bubble absorber, and then through the snake tube condensation lv, to the absorber to feed the content of 30% of hydrogen peroxide, and through the NaOH liquid (160g / L), the reaction at 0 ~ 2 ℃. After the reaction, it was filtered, and then the filtrate was vacuum evaporated to 350~400g/L, moved to the crystallizer, crystallized at -5~-10°C, and dried with air below 70°C to obtain Sodium chlorite powder.
