Abstract

Abstract : Mono-copper substituted phosphotungstate was supported on hydrous zirconia by wet impregnation, characterized and evaluated for its catalytic activity in the solvent-free flexible oxidation of styrene using TBHP as oxidant. Abstract : A heterogeneous catalyst comprising mono-copper substituted phosphotungstate and hydrous zirconia was synthesized using wet impregnation method, characterized by various physico-chemical techniques and evaluated for solvent-free oxidation of styrene using TBHP as oxidant. Various reaction parameters like time, catalyst amount, amount of TBHP and temperature were optimized with focus on optimum selectivity of styrene-oxide. Further, the catalytic activity was compared with that of unfunctionalized PW11 Cu to understand the role of the support. Finally, the role of each component of the reaction was clearly elucidated by a detailed kinetic study of the reaction using both the catalysts.
