UN3252 Industrial Air Conditioner Refrigerant Gas Sulfur Dioxide SO2 Gas for Refrigerant Systems Colorless Liquid
SO2 is a bent molecule with C2v symmetry point group. A valence bond theory approach considering just s and p orbitals would describe the bonding in terms of resonance between two resonance structures.
Sulfur dioxide is primarily produced for sulfuric acid manufacture (see contact process). In the United States in 1979, 23.6 million tonnes (26,014,547 US short tons) of sulfur dioxide were used in this way, compared with 150 thousand tonnes (165,347 US short tons) used for other purposes. Most sulfur dioxide is produced by the combustion of elemental sulfur. Some sulfur dioxide is also produced by roasting pyrite and other sulfide ores in air.
Sulfur dioxide is toxic in large amounts. It or its conjugate base bisulfite is produced biologically as an intermediate in both sulfate-reducing organisms and in sulfur-oxidizing bacteria, as well. The role of sulfur dioxide in mammalian biology is not yet well understood. Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering–Breuer inflation reflex.

Typical Applications
Precursor to 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.
As a preservative reducing agent:
Sulfur dioxide is sometimes used as a preservative for dried apricots, dried figs, and other dried fruits, it is also a good reductant.
As a refrigerant:
Being easily condensed and possessing a high heat of evaporation, sulfur dioxide is a candidate material for refrigerants.
