Improved method for the continuous production of aldehydes or unsaturated nitriles by the reaction in the gaseous phase at high temperature of monoolefins and oxygen or ammonia and oxygen in the presence of a solid oxidizing catalyst in the liquid state characterized in that oxygen or oxygenated gases are introduced into the exhaust pipe of said cyclone, the tube of which the catalyst leaving inside the cyclone is recirculated to the catalytic layer in such a way as to generate a continuous reactive oxidant.
