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.
Leather tanning industry for processing, make the leather soft, plump, tough,
waterproof, bending, wear and other properties. The chemical industry for the
production of vanillin hydroxyl, hydroxylamine hydrochloride and so on.
Sensitive industries such as reagent. The food industry as a bleaching agent,
preservatives, leavening agent, antioxidant, color agents and the insurance agent.
According to China GB2760-86 provides that: as a preservative for the wine, the
greatest use of 0.25g/kg; as bleaching agent for glucose, sugar, bamboo, rattan
and other mushrooms, no more than 0.45g/kg; residue (SO2 total), bamboo shoots,
mushrooms are not allowed more than 0.025k/kg.
