The various salts of 12-molybdophosphoric acid were used for the oxidation of methacrolein and the isomerization of n-butene. The structure of the heteropoly compounds was identified with the aid of infrared spectroscopy, x-ray diffraction, and thermal analysis. The catalytic activity, acidity, and the reaction rate for oxidation of methacrolein were determined by micro-reactor with gas chromatography. The oxidation rate was proportional to the partial pressure of methacrolein and independent of those of oxygen and steam. The catalytic activity of alkali and alkaline earth metal salts was inversely proportional to the electro-negativity of metal elements. It was also revealed that the acidity of catalysts was strongly correlated with the catalytic activities for the oxidation of methacrolein and the isomerization of n-butene.
