Abstract
A redox ammoximation process in which a ketone or aldehyde is reacted with ammonia and oxygen in the presence of a catalyst, wherein: the catalyst is an aluminophosphate based redox catalyst having the qualitative general formula (I) M1M2AlPO-5 (I) in which M1 is at least one transition metal atom having redox catalytic capability; M2 is at least one metal atom in the (IV) oxidation state; M1 and M2 are different from each other; and a proportion of the phosphorous atoms in the M1M2AlPO-5 type structure are replaced by M2 atoms.
