ABSTRACT:
A process for preparing a multi-component catalyst for producing methacrylic acid containing phosphorus, molybdenum and vanadium comprising using in preparing the catalyst, at least one number selected from the group consisting of the oxide, carbonates, acetates and hydroxides of each catalyst-constituting element as a source of the element; dissolving or dispersing the selected sources of the catalyst-constituting elements in water; adding at least one member selected from the group consisting of ammonium carbonate, ammonium hydrogen-carbonate, ammonium sulfate and ammonium hydrogen-sulfate to the resulting aqueous solution or dispersion; removing water therefrom and then heat-treating the residual product.
