Oxidative conversion of isopropyl alcohol to acetone over modified zeolite catalysts

The catalytic activity of zeolites; A-type, natural clinoptilolite and mordenite modified with Cu 2+ and Pd 2+ cations via ion exchange was studied in the oxidative conversion of isopropyl alcohol to acetone under the action of oxygen.It is established that the highest activity and selectivity in this reaction is exhibited by natural mordenite containing 0.5% (wt.)Cu 2+ and 0.1% (wt.)Pd 2+ .The kinetics of this catalytic reaction is studied in the range of: temperature 150-250 0 C, space velocity 1000-2500 h -1 and different molar ratios of the reactants and inert diluent.Based on the experimental data, a possible stepwise mechanism is proposed and theoretically grounded kinetic model of the process is developed.
