Abstract

A process for the preparation of acrylic acid and methacrylic acid, by reaction of propylene or isobutylene with molecular oxygen at an elevated temperature in the presence of an oxidation catalyst, characterized by a) carrying out the reaction in a fluidized bed reactor where the oxidation catalyst is kept in a practically undivided reaction zone, such that the oxidation catalyst can move to any point in the reaction zone; and b) using as the oxidation catalyst a catalyst containing two different catalysts the first catalyst being one that is especially effective for the oxidation of propylene or isobutylene to acrolein or methacrolein, and the second catalyst being one that is especially effective for the oxidation of acrolein or methacrolein in acrylic acid or methacrylic acid.
