Abstract

PURPOSE: To obtain a catalyst excellent in the selectivity and the yield ratio of methacrylic acid by adding Be or the like and Cu or the like to a heteropoly- acid having an almost salt structure consisting of P, Mo, V and O prepared in the presence of a nitrogen containing heterocyclic compound.
CONSTITUTION: As the oxidizing catalyst for preparing methacrylic acid or the like by subjecting 4C unsaturated hydrocarbon to catalytic gas phase oxidation, one wherein a heteropoly-acid is molybdophosphoric acid or a partially substituted compound thereof having an almost salt crystal structure of which 2θ is about 26.2°, 10.5°, 21.3° and 30.3° in X-ray pattern and a general formula is PaMobVcXdYeOf wherein X is Be, Ca or the like, Y is Cu, Ag or the like, when b is 12, a is 0.1W3, c is 0W6, d is 0.05W5, e is 0.01W5 is used. This catalyst prepares methacrylic acid in high selectivity and a high yield ratio.
