Abstract
The present invention relates to a catalyst for producing methacrylic acid by the vapor-phase catalytic oxidation of methacrolein, comprising Mo, V, P and Cu as the indispensable active components, wherein copper acetate is used for all or a part of the necessary amount of a material for said Cu, a coated catalyst and a method for manufacturing the coated catalyst, and methacrolein is reacted in a high conversion and methacrylic acid is produced in a high selectivity by use of the catalyst of the present invention, and the catalyst can be used for reaction under high loading condition.
