Abstract: The photochemical reactions of sulfur dioxide and i-pentane in the presence or absence of oxygen systems were studied.Aerosol and a series of products such as alcohols, aldehydes, ketones, acids, esters, hydrocarbons and organic sulfur compounds were identified by GC/MS.According to the characters of such compounds and the free radical theory, the mechanism of these photo-chemical reactions were suggested.These results are very important in the studies of chemistry of air pollution.

Key words: Sulfur dioxide, i-Pentane, Photochemical reaction
