Oxidation of 1-butene by nitrous oxide over manganese(III) and related transition metal oxides

Abstract

The oxidation of 1-butene by nitrous oxide over manganese(III) oxide was studied in a continuous flow system from 573 to 673 K. Kinetic parameters were derived from the exponential relationship:[Formula: see text] over reactant partial pressure ranges, [Formula: see text] and [Formula: see text]. The reaction mechanism proposed involves a complex sequence of steps which include surface radical reactions. On the basis of a comparison of specific reaction rates, the catalytic activity series for the reaction over a number of transition metal oxides was: CuO > Fe2O3 > NiO > Mn2O3 > Cr2O3 > TiO2 > Sc2O3 > SnO > ZnO > V2O5 > AlO3.
