PRODUCTION OF CATALYST FOR SYNTHESIS OF METHACRYLIC ACID

摘要

PURPOSE:To provide a novel method for producing a catalyst used in synthesis of methacrylic acid from methacrolein by vapor phase catalytic oxidation. CONSTITUTION:When a catalyst contg. at least Mo, P and V as effective components is produced, an aq. slurry of the catalytic components is dried and water and/or alcohol is added to the resulting dried product by 5-60wt.%. They are mixed and molded to form a molded catalyst and this catalyst is rozen and heat-treated. The objective catalyst having increased pore volume and enhancing the yield of methacrylic acid can be produced.
