ABSTRACT:
A process for producing a catalyst comprising an antimony-containing oxide which comprises the steps of (A) calcining a mixture of metal oxides containing, as essential components, an oxide of antimony and an oxide of at least one metal selected from the group consisting of iron, cobalt, nickel, manganese, uranium, tin and copper, said calcining being at temperatures of from about 500.degree. C to about 1000.degree. C; (B) impregnating with or spraying onto said calcined mixture of metal oxides (a) an aqueous solution or a suspension containing (1) at least one compound of a metal selected from the group consisting of molybdenum, vanadium and tungsten, said metal compound being thermally convertible to an oxide of said metal, and (2) a tellurium compound, said tellurium compound being thermally convertible to a tellurium oxide, or (b) an aqueous solution or a suspension containing said metal compound (1) and an aqueous solution or a suspension containing said tellurium compound (2); (C) drying said impregnated or sprayed mixture of metal oxides and (D) calcining said dried mixture of metal oxides at a temperature of from about 400.degree. C to about 850.degree. C, wherein said calcining (D) is at a temperature lower than said calcining (A).
