Air Liquide manufactures sulfur dioxide pure gas with purity up to 99.9% to be used in a variety of applications, including chemical synthesis, pesticides and disinfectants.

Sulfur dioxide (SO2) in wine is used as a preservative because of its anti-oxidative and anti-microbial properties.  Also SO2 is used as a cleaning agent for barrels and winery facilities.
