(Printing and dyeing, photography, etc.), used as bleach mordant, reducing agent rubber coagulant, also used in organic synthetic pharmaceuticals and spices.


Sodium metabisulfite is a white or yellow crystalline powder or small crystal with a strong SO2 odor, a specific gravity of 1.4, soluble in water, and the aqueous solution is acidic. When it is in contact with a strong acid, it releases SO2 to form a corresponding salt. When it is left in the air, it oxidizes. It is Na2S2O6, so the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.





Uses of sodium metabisulfite


Used as bleaching agent, mordant, reducing agent, rubber coagulant, also used in organic synthesis, pharmacy and perfume, etc.


Used as chromatographic analysis reagent, preservative and reducing agent, used in dye and pharmaceutical industry

China stipulates that it can be used for candied fruit, biscuits, sugar, rock sugar, caramel, candies, glucose, liquid glucose, bamboo shoots, mushrooms and canned mushrooms. The maximum use amount is 0.45g/kg. The residual amount of candied fruit, bamboo shoots, mushrooms and canned mushrooms, grape and blackcurrant concentrated juice (calculated as SO2) is less than 0.05/kg; the residual amount of biscuits, sugar, vermicelli and other varieties is less than 0.1g/kg; the residual amount of liquid glucose No more than 0.2g/kg.


In the food industry, it is used as a bleaching agent, preservative, bulking agent, antioxidant, color protectant and preservative.


The pharmaceutical industry is used to produce chlorofor, phenylpropansulfone and benzaldehyde. Used as a coagulant in the rubber industry.
