The photochemical reaction of pentane and sulfur dioxide were studied. A se
ries of gaseous products such as alcohols ketones, esters, sulfuric anhdrid
e, carbon monooxide, carbon dioxide were identified by GC/MS and GC. The re
action kinetics and reaction mechanism were investigated. The influence of
initial concentration of reactant on the photochemical reaction of pentane
and sulfur dioxide was studied.
