大气光化学反应研究(Ⅱ)——二氧化硫与异戊烷的光化学反应

An Investigation of the Photochemical Reactions ( Ⅱ ) ——The Photochemical Reactions of Sulfur Dioxide and i-Pentane

研究了SO_2与异戊烷在无氧和有氧体系中的光化学反应,用GC和GC-MS法确证了部分气、液相产物,包括醇、醛、酮、酯和烃类及含硫有机物,探讨了影响光化学反应的因素和反应机理.

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.
