Abstract

Two mixed oxides of vanadium and phosphorus, with phosphorus to vanadium atomic ratio (P/V) about 2 and 2.4, were studied as catalysts for selective oxidation of butane to maleic anhydride. The sample with P/V about 2 was poorly crystalline, contained a small amount of V(V), and oxidized butane to maleic anhydride with about 50% selectivity. The sample with P/V about 2.4 contained well crystalline VO(PO3)2 phase, but it deactivated with time-on-stream with the formation of V(PO3)3. The results suggested that the two samples differed greatly in their rates of oxidation of the vanadium ions.
