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, it is also a good reductant.
Being easily condensed and possessing a high heat of evaporation, sulfur dioxide is a candidate material for refrigerants.
