Titanium silicate molecular sieve (TS-1)/H2O2 induced triphase catalysis in the oxidation of hydrophobic organic compounds with significant enhancement of activity and Para-selectivity

Abstract

Triphasic conditions (solid and two immiscible liquid reactants) when compared with more commonly employed biphasic ones (solid and immiscible liquids along with a cosolvent), significantly enhance the catalytic activity and para selectivity in the hydroxylation/oxidation of various hydrophobic organic compounds (viz. toluene, anisole, benzyl alcohol, cyclohexanol etc.)over crystalline, microporous, titanium silicate, TS-1, using dilute H₂O₂(30 mass%, aq.).
