摘要

A process for catalytic dehydrogenation, in particular an alkene or an alkadiene with 3 to 10 carbon atoms per molecule; a cycloalkene or a cycloalkadiene with 4 to 10 carbon atoms per molecule; an alkylpyridine with, per molecule, from 1 to 4 alkyl groups, at least one of which contains at least 2 carbon atoms; or an aromatic alkyl hydrocarbon in which at least one alkyl group contains at least 2 carbon atoms; thus obtaining a dehydrogenated and/or oxygenated product by contact with free oxygen in the presence of an iron phosphate catalyst; characterized in that an iron phosphate catalyst is employed in which the p: fe ratio is 1.001 to 5 times the stoichiometrically necessary ratio to form a neutral iron orthophosphate and the o: p ratio is between 3: 1 and 3,999: 1.
