Sulfur dioxide is a common sulfur oxide, is a colorless gas, has a strong strong pungent smell. One of the main pollutants in the atmosphere, this gas is emitted by volcanoes and produces sulfur dioxide in many industrial processes. Because coal and oil usually contain sulfur compounds, sulfur dioxide is formed when burned. Sulfur dioxide is a toxic gas, but sulfur dioxide chemical, life, industry and other fields widely used!

Use 1: Preservative

    Because of its antibacterial properties, sulfur dioxide is sometimes used as a preservative in dried apricots and other dried fruits, to maintain the appearance of the fruit and to prevent decay

Use 2: Brewing wine

    Sulfur dioxide is a very useful compound in wine making. It ACTS as an antibiotic and antioxidant, preventing the wine from being damaged and oxidized by bacteria. It also helps to maintain the desired level of volatile acidity

Use 3: Reducing bleaching agent

    Sulfur dioxide is also a good reducing agent. In the presence of water, sulfur dioxide can discolor substances. In particular, it is a useful bleach for paper and clothing. This bleaching usually does not last long. Oxygen in the air reoxidizes the reduced dye, restoring the color to the precursors of sulfuric acid

    Sulfur dioxide is also used to prepare sulfuric acid, which is first converted to sulfur trioxide, then to fuming sulfuric acid, and finally to sulfuric acid.

Purpose: refrigerant

    Sulfur dioxide is suitable for use as a refrigerant because of its easy liquefaction and high heat of vaporization

Use: reagents and solvents

    Liquid sulfur dioxide is a universal inert solvent widely used to dissolve strong oxidizing salts.

Usage: Dechlorination

    In urban sewage treatment, sulfur dioxide discharge before used to handle wastewater chloride, sulfur dioxide in life, chemical industry, widely used in industry, it is more need our attention to the leakage of the gas, avoid to our life, production losses, sulfur dioxide gas alarm installation can effectively prevent the loss caused by sulfur dioxide gas leak to us!
