SPECIFICATIONS
Our Sulfur oxide (SO2) meets Chinese national standards, as well as European and American standards.
PHYSICAL PROPERTIES
Sulfur dioxide is the chemical compound with the formula SO2. It is a toxic gas responsible for the odor of burnt matches.
APPLICATION
The overarching, dominant use of sulfur dioxide is in the production of sulfuric acid.Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid.
Sulfur dioxide is sometimes used as a preservative for dried apricots, dried figs, and other dried fruits, owing to its antimicrobial properties and ability to prevent oxidation.
Sulfur dioxide used in Winemaking.
Sulfur dioxide is also a good reductant.
Sulfur dioxide as a fumigant.
Sulfur dioxide as a reagent and solvent in the laboratory
Sulfur dioxide as a refrigerant
