Abstract

Procedure for the production of unsaturated nitriles, according to the ammoxidation reaction, characterized in that a mixture consisting of an olefin, ammonia and oxygen or oxygen-containing gases is fed to the synthesis reactor, filled with an antimony-based catalyst, together with a recycled amount corresponding in part or in whole to one or more of the non-condensable gases in water leaving said reactor.
