Catalytic reactivity of Cr/SiO2 in the liquid phase oxidation of cyclohexanol by tert-butyl hydroperoxide

Abstract

Silica supported chromium is a heterogeneous, active and selective catalyst for the liquid phase oxidation of cyclohexanol by tert-butyl hydroperoxide (TBHP) in the presence or absence of oxygen. It is also active for the decomposition of TBHP. The reactivity at 70°C and atmospheric pressure is higher than over other catalysts and the cyclohexanone selectivity is 100%.
