Abstract: Isobutyraldehyde is oxidized to methacrylic acid by contacting gaseous isobutyraldehyde with molecular oxygen at oxidative conditions in the presence of a catalyst of the empirical formula: Mo12P0.1-3Cu0.01-2V0.01-3M0.1-3M'0.01-2Ox where M is at least one of K, Rb, Cs and Tl; M' is at least one of Be, Mg, Ca, Sr, Ba, Nb and Sb; and x is a positive number that satisfies the valence requirements of the other elements present.

Abstract: 5230 The invention herein is directed toward a process for the conversion of oxides of nitrogen to nitrogen gas by employing a reactant carbon fiber or inter host carbon material at a temperature of about 550.degree. C. The reactant material can be utilized alone or on a support material; in reactors such as fixed bed, fluid bed and radial flow; and, if desired, can be regenerated during the conversion process.
