ABSTRACT:
Novel maleic anhydride catalysts comprising phosphorus-vanadium oxides and phosphorus-vanadium-co-metal oxides wherein said catalysts do not expand under reaction conditions for the manufacture of maleic anhydride and a process for preparing these catalysts are disclosed. The process comprises reacting a vanadium compound with a phosphoryl halide in the presence of water in an atmosphere comprising at least about 0.1% oxygen wherein the molar ratio of water to phosphorus from the phosphoryl halide is in the range of about 2.25:1 to about 3.75:1.
