Under solvent-free triphase conditions (solid catalyst TS-1, organic substrate and aqueous H2O2, S-L-L) a significant enhancement in the reaction rate (ca by 15–25 times) during the oxidation of benzene, compared to that obtained under conventional biphase system using an organic solvent (solid TS-1 catalyst in the presence of a cosolvent to homogenize the organic and aqueous layers, S-L), was observed. Time-dependent studies in the hydroxylation of benzene over TS-1/H2O2system indicated that… CONTINUE READING
