METHOD OF PREPARING CATALYST FOR PRODUCTION OF METHACRYLIC ACID

摘要

　Provided is a catalyst with which methacrylic acid can be produced at high selectivity. Also provided is a method for preparing a catalyst of consistent quality, during repeated preparation of a catalyst. The method for preparing a catalyst for production of methacrylic acid is characterized by including (a) a step of dividing a catalyst starting material into at least two parts, dispersing or dissolving each of the catalyst starting materials within respectively different preparation tanks to obtain a catalyst starting material slurry or catalyst starting material solution as a prepared liquid, and (b) a step of mixing the entire catalyst starting material slurry or catalyst starting material solution within a single mixing tank, the preparation tanks and the mixing tank being different.
