ABSTRACT OF THE DISCLOSURE Acrylic acid and methacrylic acid are prepared by reacting propylene or isobutylene with molecular oxygen at a temperature of about 200° to about 600°C. in a fluid-bed reactor using a catalyst charge containing two different catalysts--the first catalyst being one that is especially effective for pre- paring the acrolein or methacrolein from the propylene or isobutylene; and the second catalyst being one that is especially effective for preparing acrylic acid or methacrylic acid from acrolein or methacrolein. Unexpectedly high yields of acrylic acid and methacrylic acid are obtained.
