Abstract
Selective oxidation of alkanes, aromatic compounds such as benzene and phenol, alcohols and thioethers has been carried out over titanium and vanadium analogues of ZSM-11 (MEL structure, termed as TS-2 and VS-2, respectively) with aqueous hydrogen peroxide. The results show interesting similarities and contrasts between TS-2 and VS-2. VS-2 produces more secondary oxidation products. It is also more effective in oxidizing alcohol and thioethers than TS-2. The differences are attributed to the differences in the mechanism of oxidation of the different substrates over TS-2 and VS-2. While a predominantly heterolytic oxidation is postulated in the case of TS-2, the principal path is probably homolytic in the case of VS-2.
