    Nature:

     

    white or light yellow crystalline powder , relative density is 1.4 . Soluble in

    water (when20 ° C, 54g/100ml water; when 100 ° C, 81.7g/100ml water),

    acidic aqueous solution. Soluble in glycerine, slightly soluble in ethanol.

    Moisture easily decomposed, exposed in the air easily oxidized into

    sulfate. Exposure to emit sulfur dioxide and acid generated the corresponding

    salts. Heated to 150 ° C decomposition.

     

    Usage:

     

    Pharmaceutical industry for the production of chloroform, benzene, styrene
    sulfone, and formaldehyde. Rubber industry as a coagulant. Bleached cotton
    printing and dyeing industry as the dechlorination agent, cotton scouring agent.
