Abstract

The oxidative degradation of thiophene, 2-methyl- and 3-methyl-thiophene, and their intermediate oxidation products, by the Fenton and related reagents, has been studied. Hydroxylated thiophenes were the main intermediate oxidation products, but a range of other apparently radical-derived oxidation products was also characterized. The ease of oxidisability was established as thiophene > 2-methylthiophene > 3-methylthiophene. Of the metal ion-hydrogen peroxide reagents studied, the Fenton system (Fell) was generally the most effective and the range of oxidation products formed was largely independent of the reagent used.
