Abstract

A catalyst for the production of acrylic acid by the vapor-phase catalytic oxidation of acrolein or acrolein-containing gas and a method for the production of acrylic acid by the use of this catalyst are provided. The catalyst of this invention comprises (A) a catalyst having Mo and V as essential components and used for the production of acrylic acid by vapor-phase catalytic oxidation of acrolein and (B) a solid acid having acid strength (Ho) of not more thav -11.93. Since this catalyst excels in catalytic activity and service life, it allows acrylic acid to be produced stably at a high yield for a long time.
