    • An improved process for producing maleic anhydride which comprises catalytically oxidizing benzene with a molecular oxygen-containing gas in the vapor phase in a multitubular heat-exchanger-type reactor. The process is characterized in thata catalyst-packed layer of the reactor is divided into a gas inlet side layer and a gas outlet side layer,the activity of the gas inlet side layer is controlled by adding at least one component selected from the group consisting of potassium, cesium, thallium and rubidium as a promoter or by decreasing the amount of phosphorus pentoxide (P.sub.2 O.sub.5) to be added in the catalytically active substance containing vanadium pentoxide, molybdenum trioxide and sodium oxide, andthe activity of the gas outlet side layer is increased by decreasing the amount of at least one component selected from the group consisting of potassium, cesium, thallium, rubidium, magnesium, calcium, strontium and barium or by not adding such a component from that in the catalyst, or by increasing the amount of phosphorus pentoxide (P.sub.2 O.sub.5) from the gas inlet side catalyst.
