摘要：

A mechanism and rate expressions are proposed to explain the conversion kinetics of isobutyric acid to methacrylic acid by oxidative dehydrogenation on several iron phosphate catalysts. The relation between the catalyst nature and rate constants led us to suggest improvements in the catalysts and in reaction conditions. The mechanism proposed involves surface hydroxyl groups and sites composed of two nearby Fe cations. It corresponds to a new extension of the well-known Mars and Van Krevelen mechanism, often postulated for partial oxidation reactions on oxides.
