Abstract

Process for the continuous production of unsaturated aldehydes and nitriles, by means of the high temperature vapor phase reaction between monoolefins and oxygen or ammonia and oxygen, in the presence of a solid oxidation catalyst, in the fluidized state in a reactor provided with at least one cyclone for the recovery of the catalyst mechanically entrained by the reaction gases, characterized in that oxygen or oxygen-containing gases are fed into the discharge tube of said cyclone and, through said tube, the catalyst, separated in the cyclone, it is recycled to the catalytic bed so as to form a continuous oxidative regeneration zone within the reactor.
