Abstract: The photooxidation of diethyl sulfide to diethyl sulfoxide was studied in methanol solution by using polymeric Hose Bengal as singlet oxygen sensitizer.Experimental results have led to the following relation for the reaction rate of pho-tooxidation which is in agreement with the kinetic equation obtained under photostation-ary conditions:ROx=K[R2S]0[O2]0.42[I]
