    Sodium bisulfite Usage And Synthesis
    Chemical properties white monoclinic crystal; sulfur dioxide odor; soluble in water, slightly soluble in alcohol.
    Uses 1. Used as reducing agent, food preservatives and bleach.
    2. Used for the bleaching of cotton fabric and organic substance. Used as reducing agents in dyes, paper, leather, chemical synthesis and other industries. Used for the production of analgin and aminopyrine intermediates in pharmaceutical industry. Used as bleach, preservatives, and antioxidants of food grade products.
    3. Sodium bisulfite is reduction bleach allowed to use in China. It has bleaching effect on food and has a strong inhibitory effect on the oxidase within plant foods. It can be used for candied fruit, glucose, sugar, rock candy, caramel, candy, liquid glucose, dried fruit, dried vegetables, vermicelli, bamboo shoots, mushrooms and mushroom cans in provisions of our country, with a maximum use of 0.45g/kg; it can also be used for potato starch with a maximum use amount of 0.2g/kg and a maximume residual amount (in terms of SO2) of less than 0.03 g/kg.
    4. Used as reductants in analysis and also as bleach and bacterial inhibitors
    5. Used as reducing agent, antiseptic, disinfectant and bleach.
    Identification test Both sodium salt test (IT-28) and sulfite test (IT-30) are positive.
    Content Analysis Transfer 50ml of 0.1mol/L iodine solution into a flask with a stopper, and then add 200mg of accurately weighed sample and plug. After placed 5min, add 1ml of hydrochloric acid, and plus starch test solution (TS-235) as an indicator. Titrate the excess iodine with 0.1 mol/L sodium thiosulfate. Each mI of 0.1mol/L iodine solution is equivalent to 3.203mg of sulfur dioxide (SO2).
    Toxicity ADI 0~0.7mg/kg (in SO2; including SO2 and sulfites; FAO/WHO, 2001).
    LD50 115 mg/k (rat, oral).
    GRAS (FDA, § 182.3739, 2000).
    Usage limits GB 2760-2001 (g/kg): candied fruit, dried fruits, dried vegetables, vermicelli, glucose, sugar, rock candy, caramel, candy, liquid glucose and cans of bamboo shoots, mushrooms and mushrooms 0.45; potato starch 0.20 (Residue≤0.03); fresh glucose (tablet gasification process, in sulfite) 2.4 (residual amount calculated in SO2≤0.05, tablet packaging shall give clear indication of indicate edible)
    FAO/WHO(1984): frozen shrimp, prawns, lobsters (raw product) 100mg/kg, (cooked products) 30mg/kg(in SO2); frozen french fried potatoes 50mg/kg (in SO2); pineapple juice with anti-corrosion 500 mg/kg of (in SO2; only for manufacture).

    When applied to dry fruit, sodium bisulfite can be prepared into 0.2% to 3% solution to take dipping or spraying.
    FDA, § 182.3739 (2000): shall not be used for meat, vitamin B and source food.
    EEC (1990): mainly for the preservation of alcoholic beverages.
    Production method Add sodium sulphite mother liquor (containing NaHSO3 40%, Ph value of 3 to 4) slowly into soda ash to generate sodium sulfite solution (to the slurry Ph value of 7~8 for the end); transfer the above sodium sulfite solution into series reactors (2 to 3) to absorb the SO2 gas (10% to 13%) from the combustion of sulfur, forming sodium bisulfite (to the reaction temperature no longer rising for the end). In the reaction process, a large number of crystals precipitate out, which is centrifuged to obtain the wet goods with moisture content of 6% to 10%, and then dehydrated by air drying at 250 to 300 ° C to make the final products.
    2NaHSO3 + Na2CO3 → 2Na2SO3 + H2O + CO2↑
    Absorb sulfur dioxide from the gas of sulfuric acid production with soda ash solution to generate sodium bisulfite. After further centrifugal separation and air drying at 250~300 ° C, the final sodium bisulfite is obtained.
    Na2CO3 + 2SO2 + H2O → 2NaHSO3 + CO2↑

    General Description White crystals or crystalline powder. Slight sulfurous odor. Specific gravity 1.48. Strong irritant to skin and tissue.
    Air & Water Reactions Water soluble.
    Reactivity Profile Sodium bisulfite is a reducing agent. Emits highly toxic gaseous sulfur dioxide gas when heated to decomposition or on contact with mineral acids [Sax, 9th ed., 1996, p. 2949].
    Health Hazard Powder is irritating to eyes, nose, and throat and can irritate skin. Ingestion may cause irritation of stomach. Very large doses cause violent colic, diarrhea, depression, and death.
    Fire Hazard Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
