ABSTRACT:
A method for the production of methacrylic acid comprising the steps of simultaneously introducing at least one compound selected from the group consisting of methacrolein and isobutyl aldehyde and a molecular oxygen-containing gas into a heat exchanger type shell-and-tube reaction vessel packed with an oxide catalyst containing molybdenum and phosphorus thereby effecting catalytic vapor-phase oxidation reaction and/or catalytic vapor-phase oxidative dehydrogenation reaction and consequently forming methacrylic acid, which method is characterized by having the empty space in the gas outlet part of said reaction vessel with a solid filler.
