Abstract

PURPOSE: A process for preparing methacrylic acid comprises employing the heat-resisting, stable catalyst containing 12-phosphorous acid molybdate, and the other molybdenum compound or the vanadium compound to obtain methacrylic acid by the vapor phase oxidative-dehydrogenation of isobutyric acid.
