A VPO catalyst prepared in an organic medium has been studied by in situ laser Raman spectroscopy under reaction conditions for n-butane oxidation to maleic anhydride. Data were obtainable at low laser power and short collection times. Raman characterization during continuous flow (steady state) revealed that the (VO){sub 2}P{sub 2}O{sub 7} phase was present. Sequential oxidizing (10% O{sub 2} in N{sub 2}) and reducing (2% n-butane in N{sub 2}) conditions were explored at 350{degree} and 400{degree}C. Cycling (unsteady state) revealed enhancement of {alpha}{sub II}-VOPO{sub 4}, {beta}-VOPO{sub 4}, {gamma}-VOPO{sub 4}, and {delta}-VOPO{sub 4} during oxidizing conditions; intensity of Raman bands due to (VO){sub 2}P{sub 2}O{sub 7} increased d...
