Title : Toxicological profile for sulfur trioxide and sulfuric acid Personal Author(s) : Liccione, John J.;Little, Joseph D. (cdc.gov)
High yields (95%) of tetrabromophthalic anhydride are achieved by the bromination of phthalic anhydride in 60% oleum (concentrated sulfuric acid with sulfur trioxide). (nih.gov)
The compound can also be prepared by the reaction of phthalic anhydride and bromine in a mixture of concentrated sulfuric acid and hydrogen peroxide in the presence of iodine or in chlorosulfonic acid containing small amounts of sulfur. (nih.gov)
Some of it is oxidized into sulfur trioxide (SO3), which in turn is easily transformed, in the presence of water vapor, into a dilute sulfuric acid mist (H2SO4). (jameskrohejr.com)
Reacts1
Sulfur trioxide also reacts with other basic oxides to form sulfate aerosols-ultramicroscopic particles less than one ten-thousandth of a centimeter in diameter that are suspended in the air and can enter the lungs and lodge there. (jameskrohejr.com)

Dioxide2
One of the constituents of Illinois coal is sulfur, and when coal is burned in a power plant boiler (as about 85 percent of all Illinois coal is), that sulfur is converted into sulfur dioxide (SO2) which wafts out of the smokestack along with other gases and clouds of dust and ash. (jameskrohejr.com)
Sulfur dioxide is a corrosive, toxic gas with a smell so acrid that its presence can be detected in concentrations as low as 0.3 parts per million. (jameskrohejr.com)
