427-434
Transition metal exchanged α-zirconium phosphate, α-ZrP.M (where, M = Mn(II), Cu(II) and Fe(III)) has been prepared by ion exchange method and characterized by X-ray diffraction, scanning electron micrographs, energy dispersive X-ray analysis, Fourier transform infrared and atomic absorption spectroscopy. The catalytic activity of α-ZrP.M is tested for the oxidation of the cyclohexane in liquid phase with <em>tert</em>-butylhydroperoxide as an oxidant. In the oxidation reaction, cyclohexane is oxidized to cyclohexanol and cyclohexanone. The order of reactivity of α-ZrP.M for the oxidation of cyclohexane to cyclohexanone and cyclohexanol is: α-ZrP.Mn(II) > α-ZrP.Cu(II) > α-ZrP.Fe(III). A maximum of 6.12% conversion and 100% selectivity for KA oil (cyclohexanone (K) + cyclohexanol (A)) for oxidation of cyclohexane is observed with the α-ZrP.Mn(II)/TBHP system after 5 h of reaction. Influence of various reaction parameters, viz. concentrations of oxidant and catalyst, reaction temperature, etc., has been studied. The catalyst, α-ZrP.Mn(II), can be recycled three times under similar reaction conditions. |
