General description

Toluene, a flammable liquid with a pungent odor, is widely employed as an organic solvent. It is also used as a precursor for synthesizing benzene.

Application

Toluene undergoes alkylation in the presence of modified ZSM (Zeolite Socony Mobil)-5-class zeolite catalysts to form p-xylene with high selectivity. When doped on graphene, it acts as an electron donor leading to alteration in graphene electrical properties due to electrochemical interaction.

Toluene is degraded anoxically to CO2 by the denitrifying bacterium Thauera aromatica. Toluene first becomes oxidized to benzoyl-CoA by O2-independent reactions. Benzoyl-CoA is then reduced to non-aromatic products by benzoyl-CoA reductase. We set out to study the reactions employed for
