sulfur dioxide

Sulfur dioxide (also known as sulfur dioxide) is a compound with the chemical formula SO2. It is a poisonous gas with a pungent odor that is released by volcanoes and various industrial processes. Because coal and petroleum often contain sulfur compounds, their combustion produces sulfur dioxide unless the sulfur compounds are removed before burning the fuel. SO2 is usually further oxidized in the presence of catalysts such as NO2 to form H2SO4, thus forming acid rain. [2] Sulfur dioxide emissions are also precursors to particulate matter in the atmosphere. Both effects raise concerns about the environmental impact of these fuels.

application:

as a preservative

Due to its antimicrobial properties, sulfur dioxide is sometimes used as a preservative in dried apricots, dried figs, and other dried fruits, and is sometimes referred to as E220 when used in this way. As a preservative, it preserves the colorful appearance of the fruit and prevents rot. It is also added to sulfated molasses.

in winemaking

Sulfur dioxide is an important compound in the winemaking process and is expressed in parts per million in wine.

Sulfur dioxide exists in wine in both free and combined forms, and the combination is called total SO2.
