Abstract
A process is provided for the oxydehydrogenation of aldehydes such as isobutyraldehyde with oxygen in the presence of iron phosphorus oxide catalysts containing promoters selected from Ag, Al, B, Be, Cd, Co, Cr, Cu, Ga, Ge, In, Mn, Ni, Te, Th, Ti, Tl, U, V, Zn, Zr, rare earths and mixtures thereof.
Claims12
A process for the production of methacrolein comprising contacting isobutyraldehyde with molecular oxygen or an oxygen containing gas in the vapor phase at a reaction temperature of about 250.degree. C. to about 600.degree. C. in the presence of a catalyst having the empirical formula
- A.sub.a Fe.sub.b P.sub.c O.sub.x
- wherein
- A is selected from the group Ag, Al, Be, Cd, Co, Cr, Cu, Ga, Ge, In, Mn, Ni, Te, Th, Ti, Tl, U, V, Zn, Zr, rare earths and mixtures thereof and wherein
- a is about 0.01 to about 2.0
- b is about 0.5 to about 2.0
- c is about 1.0 to about 3.5 and
- x is the number of oxygens needed to satisfy the valence requirements of the remaining elements.
