Abstract
A process for producing an alkanesulfonic acid is described, which comprises causing sulfur dioxide and oxygen to act on a saturated hydrocarbon under illumination with light in a substantially water-free reaction system, wherein photo-sulfoxidation of the saturated hydrocarbon is performed as a reaction mixture in the reaction system is held in contact with sodium sulfite.
